2009-09-09	Till Straumann <strauman@slac.stanford.edu>

	* startup/bspstart.c: Added dummy implementation of firmware
	syscalls for use with QEMU. Dummy handler is installed if no
	pre-existing firmware handler is found.

2009-07-30  Eric Norum <norume@aps.anl.gov>

	* include/bsp.h, network/network.c, startup/bspstart.c:  Try enabling
    the data cache.

2009-07-28  Eric Norum <norume@aps.anl.gov>

   PR 1420/bsps
   * startup/bspstart.c: Turn on buffered writes to DRAM. As Device Errata
      SECF124 notes this may cause double writes, but that's not really a big
      problem and benchmarking tests have shown that buffered writes do gain
      some performance.

2009-06-02	Eric Norum <norume@aps.anl.gov>

	PR 1420/bsps
	* startup/bspstart.c: Turn off buffered writes.

2009-03-02	Till Straumann <strauman@slac.stanford.edu>

	PR 1375/bsps
	* clock/clock.c: Correct implementation of nanoseconds since last tick
	handler.

2009-01-21	Eric Norum <norume@aps.anl.gov>

	PR 1358/bsps
	* clock/clock.c: Fix time-access bug in uc5282 BSP.

2008-12-08	Ralf Corsépius <ralf.corsepius@rtems.org>

	* bsp_specs: Backport from CVS-HEAD.

2008-09-05	Ralf Corsépius <ralf.corsepius@rtems.org>

	* timer/timer.c: Convert to "bool".

2008-08-31	Joel Sherrill <joel.sherrill@oarcorp.com>

	* timer/timer.c: Eliminate empty function from every benchmark timer
	driver. Fix spelling.

2008-08-31	Joel Sherrill <joel.sherrill@oarcorp.com>

	* timer/timer.c: Rename timer driver methods to follow RTEMS
	programming conventions.

2008-05-23	Joel Sherrill <joel.sherrill@OARcorp.com>

	* console/console.c: Eliminate copies of switches to convert termios
	Bxxx constants to xxx as an integer. Use the shared
	termios_baud_to_number() routine to do the same conversion.

2008-05-19	Eric Norum <norume@aps.anl.gov>

	* Makefile.am, configure.ac, startup/bspstart.c, startup/linkcmds: Back
	out changes from 2008-05-16 -- they don't seem to work.

2008-05-16	Eric Norum <norume@aps.anl.gov>

	* Makefile.am, configure.ac, startup/bspstart.c, startup/linkcmds: Use
	shared version of bootstrap to set up workspace.

2008-05-14	Joel Sherrill <joel.sherrill@OARcorp.com>

	* Makefile.am: Rework to avoid .rel files.

2008-05-12	Joel Sherrill <joel.sherrill@OARcorp.com>

	* startup/bspstart.c: Refactored and renamed initialization routines to
	rtems_initialize_data_structures, rtems_initialize_before_drivers,
	rtems_initialize_device_drivers, and
	rtems_initialize_start_multitasking. This opened the sequence up so
	that bootcard() could provide a more robust and flexible framework
	which is easier to explain and understand. This also lays the
	groundwork for sharing the division of available memory between the
	RTEMS workspace and heap and the C library initialization across all
	BSPs.

2008-04-24	Eric Norum <norume@aps.anl.gov>

    * startup/bspstart.c: More clean up of FPGA interrupts.

2008-04-23	Joel Sherrill <joel.sherrill@OARcorp.com>

	* console/console.c: Remove all references to console_reserve_resources
	and termios_reserve_resources.

2008-04-07	Eric Norum <norume@aps.anl.gov>

    * startup/bspstart.c: Clean up non-FPGA use of EPORT interrupts.

2008-04-07	Eric Norum <norume@aps.anl.gov>

    * network/network.c: Track half/fullduplex changes from 4.7 branch.

2008-03-03	Joel Sherrill <joel.sherrill@OARcorp.com>

	* startup/linkcmds: Add wildcard to gcc_except_table section so
	programs compiled with gcc 4.3.x can link.

2007-12-17	Joel Sherrill <joel.sherrill@OARcorp.com>

	* clock/clock.c, include/bsp.h: Correct prototype of idle thread. Eric
	Norum pointed out this was wrong.

2007-12-11	Joel Sherrill <joel.sherrill@OARcorp.com>

	* clock/clock.c, include/bsp.h, startup/bspstart.c: Eliminate copies of
	the Configuration Table. Use the RTEMS provided accessor macros to
	obtain configuration fields.

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

	* Makefile.am, startup/bspstart.c: Move interrupt_stack_size field from
	CPU Table to Configuration Table. Eliminate CPU Table from all ports.
	Delete references to CPU Table in all forms.

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

	* include/bsp.h, startup/bspstart.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.

2007-11-26	Joel Sherrill <joel.sherrill@oarcorp.com>

	* startup/bspstart.c: Eliminate the interrupt_vector_table field in the
	m68k CPU Table since it is never read.

2007-11-06	Joel Sherrill <joel.sherrill@OARcorp.com>

	* startup/linkcmds: Formatting.

2007-10-14	Eric Norum <norume@aps.anl.gov>

	* clock/clock.c: Add nanoseconds since tick support.

2007-05-03	Joel Sherrill <joel@OARcorp.com>

	* startup/linkcmds: Handle .data.* sections

2007-04-12	Ralf Corsépius <ralf.corsepius@rtems.org>

	* bsp_specs: Remove qrtems_debug.

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

	* clock/clock.c, console/console.c, include/bsp.h, include/coverhd.h,
	include/tm27.h, network/network.c, start/start.S, startup/bspclean.c,
	startup/bspstart.c, startup/init5282.c, startup/linkcmds,
	timer/timer.c: Correct license URL and/or fix mistake in copyright
	notice. Both of these mistakes appear to be from code submitted after
	these changes were made previously.

2007-03-11	Joel Sherrill <joel@OARcorp.com>

	* startup/bspstart.c: Remove assignments of
	Cpu_table.do_zero_of_workspace to TRUE since TRUE is the default
	value in boot_card.c

2007-03-10	Joel Sherrill <joel@OARcorp.com>

	PR 1227/bsps
	* include/bsp.h: Remove MAX_LONG_TEST_DURATION and
	MAX_SHORT_TEST_DURATION. They are obsolete and unused.

2006-12-14	Till Straumann <strauman@slac.stanford.edu>

	* startup/bspstart.c: Changed BSP_installVME_isr() so that
	the special handling of a 'FPGA interrupt' [this FPGA is *not*
	present on the uC5282 module but is externally connected to
	IRQ1 on Eric Norum's particular 'motherboard'] is only
	activated when connecting to the special vectors > 192.
	The change allows us ordinary users [:-)] to use IRQ1
	normally, simply by connecting an ISR to vector 64+1...
	Also, BSP_enable_irq_at_pic(), BSP_disable_irq_at_pic(),
	BSP_irq_is_enabled_at_pic() were introduced (compat. with
	some PPC BSPs).

2006-12-02	Ralf Corsépius <ralf.corsepius@rtems.org>

	* configure.ac: New BUG-REPORT address.

2006-11-15	Joel Sherrill <joel@OARcorp.com>

	file and simplified initialization.

	* Makefile.am: Remove superfluous -DASM.

2006-10-17	Ralf Corsépius <ralf.corsepius@rtems.org>
