2008-07-18	Thomas Doerfler <thomas.doerfler@embedded-brains.de>

	* mpc83xx/network/tsec.c: Initialize PHY registers late enough,
	so that phy access is possible

2008-07-17	Thomas Doerfler <thomas.doerfler@embedded-brains.de>

	* rtems/powerpc/powerpc.h:
	ppc405 uses definitions distinct from ppc403 now
	* shared/src/cache_.h: Use correct powerpc.h to get cache attributes

	
2008-07-17	Thomas Doerfler <thomas.doerfler@embedded-brains.de>

	* shared/include/powerpc-utility.h:
	Fixed typo in access macros for device control registers (DCR)
	
2008-07-16	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/bspsupport/vectors_init.c: added
	features to C_exception_handler() (the default global
	handler):
	 - try to catch recursion
	 - print info about context where the exception occurred
	   (ISR or task with task ID).
	 - suspend offending task rather than spinning forever.
	
2008-07-16	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/bspsupport/vectors_init.c: must not
	align start of stack downwards (we don't 'own' memory
	below start). Instead, use original boundaries but
	align the stack pointer as required.

	Added test to verify that R13 was loaded with _SDA_BASE_
	during early initialization (low-level assembly code
	relies on it).

2008-07-16	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/cpu.c: propagate R2 to all task contexts
	even if the ABI is SVR4. Cannot hurt...

2008-07-16	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask()
	to determine which bits to set/clear from _CPU_Context_Initialize().

2008-07-16	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added
	a test to TEST_LOCK_crit so that a context switch is
	always prevented if MSR_CE is not set in the interrupt mask.
	(Support mode where the user wants to leave MSR_CE always enabled
	but abstains from calling OS primitives from the exception
	handler.)

2008-07-16	Till Straumann <strauman@slac.stanford.edu>

	* shared/include/powerpc-utility.h: Added 
	GET_INTERRUPT_MASK macro.

2008-07-16	Joel Sherrill <joel.sherrill@oarcorp.com>

	* mpc6xx/clock/c_clock.c: Add fast idle.

	* shared/include/powerpc-utility.h: Exchanged ASM and non ASM code
	sections.

	* rtems/powerpc/powerpc.h, shared/src/cache.c, shared/src/cache_.h:
	New defines PPC_NO_CACHE_ALIGNMENT and PPC_NO_CACHE_ALIGNMENT_POWER for
	CPUs with no cache.  Provide default implementations for all cache
	functions.

	* mpc83xx/include/gtm.h, mpc83xx/gtm/gtm.c: New files.

	Added support for PPC405EX (contributed by Michael Hamel)
	
2008-07-11	Sebastian Huber <sebastian.huber@embedded-brains.de>

	* Makefile.am: Install powerpc-utility.h.

	* shared/include/cpuIdent.h, shared/include/cpuIdent.c: Added e200 and
	e300 features.

	* new-exceptions/cpu.c: Removed PR288 bugfix check.

	* new-exceptions/e500_raw_exc_init.c: Added initialization for e200.
	Set IVPR register for e200 and e500 to ppc_exc_vector_base.

	* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h: Added
	vector categories for e200 and e300 cores.  Added global variable
	ppc_exc_vector_base for CPUs with IVPR register.

	* new-exceptions/bspsupport/ppc_exc.S,
	* new-exceptions/bspsupport/ppc_exc_asm_macros.h,
	* new-exceptions/bspsupport/ppc_exc_bspsupp.h,
	* new-exceptions/bspsupport/ppc_exc_hdl.c,
	* new-exceptions/bspsupport/vectors.h,
	* new-exceptions/bspsupport/vectors_init.c: 
	Conistent code layout in most assember code sections and usage of
	defines for registers.  Usage of standard header files to avoid
	multiple definitions. 
	
	Optimized exception code: Removed many branches and exploit branch
	prediction for asynchronous exceptions, moved common wrap code into
	WRAP macro to eliminate branch, static initialization of the handler
	table with a default handler to eliminate the test if a handler is
	present.  Register CR6 is no more cleared because the exeption handler
	functions are not variadic.
	
	New method to switch to the interrupt stack. It will be tested if the
	exception stack pointer is already inside the interrupt stack area.  It
	is no more necessary to disable interrupts.  The SPRG1 and SPRG2 are
	used to store the initial interrupt stack pointer and the interrupt
	stack memory area start.

	Removed variable ppc_exc_msr_irq_mask and use general interrupt disable
	mask from SPRG0 instead.

	New initialization routine ppc_exc_initialize() for bsp_start().  It
	takes the interrupt disable mask, interrupt stack start and size as
	parameters.

	Added packed prologues for CPUs with IVPR and IVOR registers to save
	memory space.

	Reverted ppc_exc_crit_always_enabled change from yesterday.

	WARNING: Tests with critical interrupt exceptions crash the system at
	least on MPC8313ERDB and MPC8349EAMDS.  There may be somewhere a
	serious bug with the new code.

2008-07-10	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/mmu/pte121.c: use general "memory" clobber
	rather than memory input operand in inline assembly
	("m" doesn't do what the manual says; see discussion
	on gcc mailing list around 2008/3/30)

2008-07-10	Till Straumann <strauman@slac.stanford.edu>

	* ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c,
	ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h:
	Removed all macro definitions which depended on
	the compiler defining a PPC CPU-model dependent
	symbol from files in cpukit.
	Macros which were not used by cpukit have been
	moved to libcpu/powerpc/rtems/powerpc/powerpc.h.

	new-exceptions/bspsupport/ppc_exc_bspsupp.h,
	new-exceptions/bspsupport/ppc_exc_hdl.c,
	new-exceptions/bspsupport/vectors_init.c:
	Fixed and enabled stack-switching algorithm which figures out
	if we already run on the ISR stack rather than relying on the
	_ISR_Nest_level.
	Added 'ppc_exc_crit_always_enabled' variable which defines
	the semantics of critical interrupts.
	Let asynchronous machine-check handling never call the dispatcher.
	We don't want to disable MSR_ME ever (to avoid checkstops)
	and hence asynchronous MEs must not use OS services anyways.

2008-07-09	Sebastian Huber <sebastian.huber@embedded-brains.de>

	* shared/include/powerpc-utility.h: Includes standard header files,
	provides common assembler macros and inline functions for low-level
	code.

2008-05-23	Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

	* mpc83xx/network/tsec.c:

2008-05-16	Joel Sherrill <joel.sherrill@OARcorp.com>

	* mpc83xx/include/mpc83xx.h: or is not a good name for any name in
	C/C++. See iso646.h for the reason.

2008-05-15	Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

	* mpc83xx/i2c/mpc83xx_i2cdrv.c:

	removed reference to outdated "old-exception-handling" PPC support

2008-03-20	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/bspsupport/irq.c: don't disable irqs
	at the interrupt controller (PIC) during initialization -- this
	caused problems where some BSPs's BSP_disable_irq_at_pic() routine
	did not ignore IRQ lines associated with cascaded PICs.
	Rely on the BSP (BSP_setup_the_pic()) to provide a good
	initial setup.

	new-exceptions/bspsupport/ppc_exc.S,
	new-exceptions/bspsupport/README,
	new-exceptions/bspsupport/ppc_exc_hdl.c:
	Thomas Doerfler clarified (thanks!) that raising an
	exception and executing the 1st instruction is not
	an atomical operation. I added a fix to the code that
	checks if a lower-priority interrupt is under way:
	we now not only test if the 'lock' variable was set
	but also check if the interrupted PC points to the
	'write lock' instruction.
	Added more comments and updated README.

2008-03-11	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/bspsupport/ppc_exc_asm_macros.h: bugfix;

	(ppc_exc_test.c).

2007-12-11	Till Straumann <strauman@slac.stanford.edu>

	* Makefile.am, new-exceptions/bspsupport/README:
	provide new irq_bspsupport.rel which was

	control over what BSPs want to use.

2007-12-11	Till Straumann <strauman@slac.stanford.edu>

2007-12-10	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/e500_raw_exc_init.c: map DEC

	Fixed wrong mapping of ASM_BOOKE_FIT_VECTOR
	(was ASM_BOOKE_PIT_VECTOR).

2007-12-10	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/raw_exception.c, new_exceptions/raw_exception.h,
	new_exceptions/bspsupport/irq.c: renamed ASM_BOOKE_PIT_VECTOR

	nomenclature.

2007-12-10	Till Straumann <strauman@slac.stanford.edu>

2007-12-06	Till Straumann <strauman@slac.stanford.edu>

	* shared/include/cpuIdent.h, shared/include/cpuIdent.c:

2007-12-06	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
	Removed all #ifdef <cpu_flavor>. All exception vectors are now

	Changed implementation of <cpu>_vector_is_valid() from 'case'
	statements to table lookup.
	Replaced 'ASM_VECTORS_CRITICAL' by a variable
	'bsp_raw_vector_is_405_critical' which is set at run-time.
	Removed PPC_MSR_EXC_BITS. The exception handling code
	(libbsp/shared/vectors/vectors.S and ../irq/irq_asm.S) now
	has a run-time check for these bits.
	Both files are now free of #if <cpu_flavor> constructs.

	* Makefile.am, configure.ac, preinstall.am,

	support for e500 CPU. Most stuff is borrowed from mpc6xx.

2007-12-05	Till Straumann <strauman@slac.stanford.edu>

	* rtems/powerpc/powerpc.h: added a #ifdef __ppc_generic
	branch. The goal is eventually to make this the starting
	point for cleanup (remove as many branches as possible;
	replace by run-time tests if necessary).

2007-12-05	Joel Sherrill <joel.sherrill@OARcorp.com>

	* new-exceptions/raw_exception.c: Conditionalize call to
	e500_setup_raw_exceptions() since that is not even in the tree yet.

	* new-exceptions/raw_exception.c: Conditionalize some BOOKE vectors.

2007-12-05	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
	Added typedef for exception classes (classic, critical, ...
	synchronous / asynchronous). ppc_vector_is_valid() now returns
	the appropriate class.

2007-12-05	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/raw_exception.c: made all <cpu>_vector_is_valid()
	subroutines that are called from ppc_vector_is_valid() 'static'.

2007-12-05	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
	Qualified all exception vector symbols that are only defined
	#ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
	If the special flavor __ppc_generic is effective the ALL
	vector symbols are available and ppc_vector_is_valid() works
	for all supported CPUs (run-time check).
	This is work towards a #ifdef <cpu_flavor> free libcpu and
	exception framework.

2007-12-04	Joel Sherrill <joel.sherrill@OARcorp.com>

	* mpc5xx/console-generic/console-generic.c, mpc8260/timer/timer.c,

2007-12-03	Joel Sherrill <joel.sherrill@OARcorp.com>

	* mpc5xx/console-generic/console-generic.c: Moved most of the remaining
	CPU Table fields to the Configuration Table. This included
	pretasking_hook, predriver_hook, postdriver_hook, idle_task,
	do_zero_of_workspace, extra_mpci_receive_server_stack,
	stack_allocate_hook, and stack_free_hook. As a side-effect of this
	effort some multiprocessing code was made conditional and some style
	clean up occurred.

2007-12-03	Joel Sherrill <joel.sherrill@oarcorp.com>

	* shared/include/cpuIdent.h: Correct conditionals and includes.

2007-11-30	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h,
	old-exception/cpu.c: define bsp_exceptions_in_RAM variable.
	This is probably only used by the simulator (were else
	can you install something to ROM ??).

2007-11-30	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/mmu/bat.c, mpc6xx/mmu/pte121.c: use new
	feature-checks from cpuIdent.h rather than filtering
	CPU types when checking for availability of high BATs
	and an MMU with hardware page-table lookup.

2007-11-30	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h:
	added support for bookE/ppc405 style CPUs where the
	decrementer works slightly differently.

2007-11-29	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/exceptions/raw_exception.c, 
	mpc6xx/exceptions/raw_exception.h: removed. mpc6xx
	uses generic version in new-exceptions.

2007-11-29	Till Straumann <strauman@slac.stanford.edu>

	* shared/include/cpuIdent.h, shared/include/cpuIdent.c:
	Added a simple 'feature check' facility. Code should
	not check for a particular CPU type if possible but
	check the respective feature bit (e.g., 'has_altivec').
	This makes it much less cumbersome to add more CPU
	types in the future.

2007-11-29	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/mmu/bat.c, mpc6xx/mmu/bat.h: Added support

2007-11-28	Till Straumann <strauman@slac.stanford.edu>

	* shared/src/cache.c: removed redundant mpc8xx versions

	* mpc5xx/irq/irq.c, mpc5xx/exceptions/raw_exception.c,
	new-exceptions/raw_exception.c: test for non-NULL-ness before calling

	no-ops if they don't want this feature.

2007-10-25	Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>

	* mpc83xx/network/tsec.c:

	mpc8xx/exceptions/raw_exception.c, new-exceptions/raw_exception.c,
	ppc403/ictrl/ictrl.c, ppc403/irq/ictrl.c: Code outside of cpukit
	should use the public API for
	rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
	public API and directly accessing _CPU_ISR_Disable and
	_CPU_ISR_Enable, they were bypassing the compiler memory barrier
	directive which could lead to problems. This patch also changes the
	type of the variable passed into these routines and addresses minor
	style issues.

2007-09-11	Joel Sherrill <joel.sherrill@OARcorp.com>

	pure input operands are modified by the asm.

2006-06-19	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/mmu/mmuAsm.S: re-checked synchronization
	requirements when manipulating the caches against the book
	and updated 'dssall', 'sync' and 'isync's accordingly.

2006-06-19	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/exceptions/raw_exception.c, mpc6xx/exceptions/raw_exception.h:
	Added altivec exception. Unfortunately, this doesn't fit
	the normal scheme of vector = exception # << 8. So we picked
	an unused vector number (currently 0xa) where we map the special
	vector 0xf20 (altivec).

2006-06-19	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/cpu.c, new-exceptions/cpu_asm.S: Never
	allow the FPU to be switched on for integer-only tasks
	(new gcc may use FP regs implicitly).
	FP context switch may be called from environment with no
	FPU available (ISR, int-only task) - switch FPU on
	for the switch and restore MSR_FP after it's done.

2006-05-16	Ralf Corsepius <ralf.corsepius@rtems.org>

	* mpc6xx/mmu/pte121.c: consistency check now warns instead
	of reporting an error when coming across a non 1:1 VSID;
	fix: triv121IsRangeMapped() needs to convert segment offset
	into a page index if the vsid argument is non-special.

2006-01-05	Till Straumann <strauman@slac.stanford.edu>

2005-11-21	Till Straumann <strauman@slac.stanford.edu>

	* new-exceptions/cpu_asm.S: the book says a context
	synchronizing instruction (isync) is necessary after flipping
	certain bits (e.g, MSR_FP) in msr -- since this could happen as
	part of a context switch I added 'isync'.

	* mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: enhancements to mpc6xx
	page table support - PTEs can now be modified even if the page table
	is already active; bugfix: address range crossing 256MB boundary was
	not handled correctly
	* mpc6xx/mmu/bat.c, mpc6xx/mmu/bat.h, mpc6xx/mmu/mmuAsm.S: moved
	assembly code to C; setdbat now supports high bats on 7450 CPUs;
	added argument checking to setdbat; added getdbat; moved early
	initialization code (clear_bats) from BSP to libcpu
	(CPU_clear_bats_early)
	* configure.ac, mpc6xx/exceptions/raw_exception.c,

	PR 822/bsps
	* mpc8xx/clock/clock.c: Currently the MBX8xx BSP does not boot,
	because some logical errors are in the startup code. Additionally,
	the mpc8xx shared clock driver does not support the clocking scheme
	of some of the board variants, which are clocked from a 32768Hz (!)
	external crystal.

2005-08-12	Phil Torre <ptorre@zetron.com>

	PR 816/bsps
	* mpc8xx/include/mpc8xx.h: The struct which describes SCC Ethernet
	mode parameters (m8xxSCCENparms_t) does not match the hardware:
	members taddr_h and taddr_l are transposed. When loading new
	multicast group addresses into the hash table, the wrong hash bit is

	PR 619/bsps
	* mpc6xx/clock/c_clock.c: The PPC decrementer must be reloaded on

	since the decrementer crossed zero in order to adjust the value to
	be re-loaded. Without the patch, the effective system clock cycle is
	increased by the exception handler latency.

	* mpc8xx/console-generic/console-generic.c: Bug found by Yacine
	<elkolli@crf.canon.fr> where the initialization or irq data
	structure was incomplete in case a SMC channel was used first and
	later a SCC one.

2001-05-17	Joel Sherrill <joel@OARcorp.com>

	* mpc6xx/exceptions/raw_exception.c, pc6xx/mmu/pte121.c: Modified
	slightly to reflect recent PowerPC re-organization and avoid
	warnings.

2001-05-15	Till Straumann <strauman@slac.stanford.edu>

	* mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
	merge of PR213.

2001-05-14	Till Straumann <strauman@slac.stanford.edu>

	* rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add  the
	following: - support for the MPC74000 (AKA G4); there is no AltiVec
	support yet, however. - the cache flushing assembly code uses
	hardware-flush on the G4. Also, a couple of hardcoded numerical
	values were replaced by more readable symbolic constants. - extended
	interrupt-disabled code section so enclose the entire cache
	flush/invalidate procedure (as recommended by the book). This is not
	(latency) critical as it is only used by init code but prevents
	possible corruption. - Trivial page table support as been added.
	(1:1 effective-virtual-physical address mapping which is only useful
	only on CPUs which feature hardware TLB replacement, e.g. >604. 
	This allows for write-protecting memory regions, e.g. text/ro-data
	which makes catching corruptors a lot easier. It also frees one
	DBAT/IBAT and gives more flexibility for setting up address maps :
	-) - setdbat() allows changing BAT0 also (since the BSP may use a
	page table, BAT0 could be available...). - asm_setdbatX() violated
	the SVR ABI by using r20 as a scratch register; changed for r0 -
	according to the book, a context synchronizing instruction is
	necessary prior to and after changing a DBAT -> isync added
	* new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
	point context.  The fpsave and fprestore routines are only used in a
	executing context which _is_ fp and hence has the FPU enabled. The
	current behavior required the FPU always to be on which is very
	dangerous if lazy context switching is used.   [Joel Note: Some
	ports explicitly enabled the FPU in the FP save and restore routines
	to avoid this.] The patch also makes sure (on powerpc only) that the
	FPU is disabled for integer tasks. Note that this is crucial if
	deferred fp context switching is used. Otherwise, fp context
	corruption may go undetected! Also note that even tasks which merely
	push/pop FP registers to/from the stack without modifying them still
	MUST be FP tasks - otherwise (if lazy FP context switching is used),
	FP register corruption (of other, FP, tasks may occur)! Furthermore,
	(on PPC) by default, lazy FP context save/restore is _disabled_.
	* shared/include/io.h: Per PR215 address the following issues: -
	_IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
	libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
	one to know the values) - the affected BSP (shared/motorola) headers
	have been fixed in a separate "libbsp/powerpc/shared" patch. - the
	DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
	PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
	instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
	BSP who is using this driver. - the DEC driver also has been fixed
	to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
	obsolete delay_in_bus_cycles().

2001-05-14	Joel Sherrill <joel@OARcorp.com>

	* shared/include/cpuIdent.c: Account for duplicate numbers.

2001-04-17	Joel Sherrill <joel@OARcorp.com>

	* shared/include/cpu.h: Added ifndef ASM.

2001-04-03	Joel Sherrill <joel@OARcorp.com>

	* Closed PR57.  The hack is OK as it allows a BSP to override or not
	at its discretion.
	* Per PR94, all rtems/score/CPUtypes.h are named
	rtems/score/types.h.
	* Per PR94, all rtems/score/CPUtypes.h are named

	* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
	$(RTEMS_TOPdir)/aclocal.

2000-10-26	Ralf Corsepius <corsepiu@faw.uni-ulm.de>

	* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
	GNU canonicalization.

2000-10-20	Joel Sherrill <joel@OARcorp.com>

	* mpc8xx/console-generic/console-generic.c: Avoid use of BSP
	definitions and rely on the new routine
	mbx8xx_console_get_configuration() to get information.  This routine
	was formerly incorrectly called
	mbx8xx_console_use_maximum_buffer_size(). binding to the exception
	code.
	* configure.in, Makefile.am: Explicitly specify whether an
	RTEMS_CPU_MODEL is using old or new exception processing.  This is
	important because when building multilib, you do not know  the
	RTEMS_CPU_MODEL.  So everything built in a multilib'ed RTEMS must be
	independent of the exception model and allow for late binding to the
	exception code.

2000-10-18	Sergei Organov <osv@javad.ru>

	* Added full support for MPC505.
	* configure.in, mpc505/Makefile.am: Modified to reflect ictrl
	addition.
	* old_exception_processing/Makefile.am: Account for ppc_offs.h.
	* old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
	* mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
	* mpc505/vectors/vectors.S: Now use constants for exception numbers.
	* mpc505/ictrl: New directory.
	* old_exception_processing/ppc_offs.h: New file.
	* old_exception_processing/cpu.h: Make Nest and Disable levels
	volatile.
	* mpc505/vectors/Makefile.am: alignment exception handler now
	included.
	* mpc505/ictrl/Makefile.am,
	mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.

2000-10-18	Joel Sherrill <joel@OARcorp.com>

	* mpc8xx/console-generic/console-generic.c: Removed include of
	<bsp.h> by adding BSP dependent routine
	mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
	check non-volatile memory for configuration.
	* mpc8xx/console-generic/console-generic.c: Removed warnings.
	* mpc6xx/clock/c_clock.h: Removed commented out reference to
	<bsp.h>.
	* mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
	* mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
	bsp.h and replaced it with use of proper interfaces or explicit
	externs of required functions and data.

2000-09-04	Ralf Corsepius <corsepiu@faw.uni-ulm.de>

	* mpc505/timer/Makefile.am, mpc505/vectors/Makefile.am,
	mpc6xx/clock/Makefile.am, mpc6xx/exceptions/Makefile.am,
	mpc6xx/mmu/Makefile.am, mpc6xx/timer/Makefile.am,

	mpc8xx/vectors/Makefile.am, new_exception_processing/Makefile.am,
	old_exception_processing/Makefile.am: Include compile.am

2000-08-11	Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>

	* mpc8xx/console-generic/console-generic.c: Add support for
	configuration parameters in NVRAM

2000-08-10	Charles-Antoine Gauthier  <charles.gauthier@nrc.ca>

	* mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite):
	Flush actual buffer.
	* mpx8xx/console-generic/console-generic.c: Addition of support for
	shared printk and no termios.

2000-06-08	Eric Valette <valette@crf.canon.fr>

	* mpc8xx/console-generic/console-generic.c: The printk/printf did
	not work when loaded by EPPCBUG. They did work when loaded with the
	BDM debugger.  I suspected EPPBUG  made some nasty things like
	patching Communication processor microcode...  Anyway, the attached
	patch: 1) Enables to have printk nearly immediately after boot, 2)
	Make printf work automagically (I do not know why except I make a 
	different initialization for printk that should be overwritten by 
	console init later ?) I let the default to be using EPPCBUG embedded
	firmware to boot and  using this printk early enabler code
	(LOADED_BY_EPPCBUG and  EARLY_CONSOLE) are on.
