* .cvsignore: Add autom4te.cache for autoconf > 2.52. * configure.in: Remove. * configure.ac: New file, generated from configure.in by autoupdate.
2001-09-272001-09-23 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-1/+6
* rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='. * Makefile.am: Use 'PREINSTALL_FILES ='.

* cpu_asm.S: This patch was co-developed with Eric Norum <eric.norum@usask.ca>. It closes a one instruction window on some m68k CPU cores. It fixes symptoms seen as: 1) No more `interrupt handler invoked twice for a single interrupt'. 2) No more `lockup when mc68360 CPM and PIT interrupts are at different levels'. It does insert a little more overhead on machines without hardware interrupt stacks but correctness has a price.

* Makefile.am, rtems/score/Makefile.am: Apply include_*HEADERS instead of H_FILES.
2001-01-032001-01-03 Joel Sherrill <joel@OARcorp.com>Joel Sherrill3-2/+11
* rtems/score/cpu.h: Added _CPU_Initialize_vectors(). * cpu_asm.S: Modify to properly dereference _ISR_Vector_table now that it is dynamically allocated.
2000-12-192000-12-19 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-1/+8
* cpu.c: Do not read or write raw interrupt vector table if we are on a CPU that does not have a %vbr register and the BSP is configured as having the table in ROM.
2000-11-092000-11-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-1/+5
* Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2000-11-022000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-1/+5
* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
2000-10-252000-10-25 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-1/+6
* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to GNU canonicalization.
2000-10-192000-10-19 Antti P Miettinen <anmietti@trshp.ntc.nokia.com>Joel Sherrill4-9/+24
* rtems/score/cpu.h: define CPU_Exception_frame for rdbg. * m68302.h: Make buffer pointer in m302_SCC_bd volatile.
2000-10-122000-10-12 John S Gwynne <jgwynne@mrcday.com>Joel Sherrill3-10/+22
* sim.h: These changes enable RTEMS to automatically generate the ram_init file used by gdb with the BDM patches. The 332 has on-board chip select lines (for RAM and FLASH) that must be configured before use of these peripherals. These patches parse data from start.c where the chip select lines are configured in the runtime executable and automatically generates the gdb initialization file using the same settings. A great time saver. A similar file, ram_init_FW (flash writable), is also generated that the flash programming tool uses. * BSP/start/start.c: Must be modified to support above. * BSP/start/ram_init.ld, BSP/start/ram_init.sed: New files.
2000-09-052000-09-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-0/+5
* Makefile.am: Include compile.am.

2000-07-11Patch rtems-rc-20000711-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill2-2/+2
that decouples exec/ for the sh, m68k and i960 from targopts.h. NOTE: The change to system.h is a hack to enable cpuopts.h for some targets, but keep using targopts.h for others - I know it does *not* work for sparc, mips, i386 and ppc. This will have to be addressed as work continues on multilibing.
2000-06-13Moved i386 and m68k cache management code to libcpu. EverythingJoel Sherrill1-211/+0
now is an implementation of the prototypes in rtems/rtems/cache.h. The libcpu/i386/wrapup directory is no longer needed. The PowerPC needs this done to it.
2000-06-12Patch from John Cotton <john.cotton@nrc.ca>, Charles-Antoine GauthierJoel Sherrill1-8/+231
<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart <Darlene.Stewart@nrc.ca> to add support for a number of very significant things: + BSPs for many variations on the Motorola MBX8xx board series + Cache Manager including initial support for m68040 and PowerPC + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use same code base. + Rework of eth_comm BSP to utiltize above. John reports this works on the 821 and 860

1999-12-01Patch rtems-rc-19991123-rc-1.diff from Ralf CorsepiusJoel Sherrill1-0/+53
<corsepiu@faw.uni-ulm.de> which implements automake support for some score/cpu/<RTEMS_CPU> subdirectories and fixes a few minor configuration bugs. To apply: rm -rf c/src/exec/score/cpu/i960/wrap rm -rf c/src/exec/score/cpu/m68k/wrap rm -rf c/src/exec/score/cpu/sh/wrap rm -rf c/src/exec/score/cpu/sparc/wrap rm -rf c/src/exec/score/cpu/unix/wrap patch -p1 < rtems-rc-19991123-rc-1.diff ./bootstrap Known bugs: * "make debug|profile" in c/src/src/score/cpu/<RTEMS_CPU/Makefile does not handle recursion to subdirectories correctly (recurses too often). However, this issue is hardly visible and should be tolerable for the moment.
1999-11-22Changed name of W, X, and Y macros for fields in the ClockJoel Sherrill2-18/+18
Synthesizer Control Register to remove use of single letter names.
1999-11-17Updated copyright notice.Joel Sherrill5-10/+5
1999-11-05This is another pass at making sure that nothing outside the BSPJoel Sherrill1-0/+12
unnecessarily uses any variables defined by the BSP. On this sweep, use of BSP_Configuration and Cpu_table was eliminated. A significant part of this modification was the addition of macros to access fields in the RTEMS configuration structures. This is necessary to strengthen the division between the BSP independent parts of RTEMS and the BSPs themselves. This started after comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
1999-07-29Patch from Charles-Antoine Gauthier <charles.gauthier@iit.nrc.ca>Joel Sherrill1-1/+1
to correct a typo CPU_HAS_OWN_HOST_TO_NETWORK_ROUTINES was actually typed in as CPU_CPU_HAS_OWN_HOST_TO_NETWORK_ROUTINES.

I wonder about the following .h files that were not moved: a29k/asm.h a29k/cpu_asm.h i386/asm.h i960/asm.h m68k/asm.h m68k/m68302.h m68k/m68360.h m68k/qsm.h m68k/sim.h mips64orion/asm.h mips64orion/cpu_asm.h mips64orion/mips64orion.h no_cpu/asm.h no_cpu/cpu_asm.h powerpc/asm.h powerpc/mpc860.h sh/asm.h sparc/asm.h sparc/erc32.h
1999-01-20Patch from Eric Norum <eric@skatter.usask.ca> to make m68360.h usableJoel Sherrill2-714/+732
outside RTEMS. Comment: I found a couple of places other than RTEMS where I'd like to use the declarations supplied in m68360.h. To make this easier to do, I've redone the declarations in m68360.h to use standard C types.
1998-12-14Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de> to rename allJoel Sherrill1-0/+291
.s files to .S in conformance with GNU conventions. This is a minor step along the way to supporting automake.

specific register macros and correct code in rtems.s.
1998-06-12Added optimized version of memcpy.c to this directory since RTEMS makesJoel Sherrill1-0/+87
important distinctions between CPU models which are not made by gcc. These distinctions help give us a more optimized memcpy(). This is important for message queues and KA9Q.

suggestion.

1997-10-08Fixed typo in the pointer to the license terms.Joel Sherrill1-2/+2
1997-08-22Corrected bug per Katsutoshi Shibuya's report:Joel Sherrill2-4/+4
The definition of "BEGIN_DATA" should not be null; should be ".data". Also, the definition of "BEGIN_BSS" should be ".bss". For this error, the compiled object has codes that write on the text segment area. It is fatal when the code runs on ROM.
1997-07-31Merged very large and much appreciated patch from Chris JohnsJoel Sherrill2-4/+110
