* rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which
is used to specify if the port uses the standard macro for this (FALSE).
A TRUE setting indicates the port provides its own implementation.
* rtems/score/c_isr.inl: Deleted and contents merged into cpu.c.
* cpu.c: Received contents of c_isr.inl.
* Makefile.am: Deleted reference to c_isr.inl.
|
|
* .cvsignore: Add aclocal.m4, autom4te.*, config.*, configure.
|
|
* Makefile.am: Preinstall c_isr.inl (HACK).
* ChangeLog: New file.

old versus new exception processing being a per BSP option.

support/old_exception_processing/cpu.h,

|
* new_exception_processing/cpu_asm.S: Support double or single
precision context switches. Note that doing a single precision
context save/restore on a double precision PowerPC machine does not
only result in rounding errors but also screws up the FPSCR register!

This modification is part of the submitted modifications necessary to
support the IBM PPC405 family. This submission was reviewed by
Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
not negatively impact the ppc403 BSPs. The submission and tracking
process was captured as PR50.

were needed to move exception processing to score/cpu.

from score/cpu to libcpu because the determination of which to use is
based on RTEMS_CPU_MODEL. Thus it can not be determined based solely on
multilib information.

<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

Ralf Corsepius <corsepiu@faw.uni-ulm.de> that contain:
* Modifications, (minor) corrections, cleanups to most existing
Makefile.ams
* Adds automake support to all remaining BSPs which have not yet been
converted to automake.
* Makefile.am for all remaining wrapup/Makefile.ams

<corsepiu@faw.uni-ulm.de>:
The patch below provides
* automake support for score/cpu/powerpc
* The hack to propagate values from *.cfg to automake configuration
* A fix for librdbg/powerpc/mcp750/Makefile.am (Was completely corrupted
before)
* Fixes some files which apparently where missing in
rtems-rc-19991123-rc-2.diff
* some minor configuration related patches
To apply:
rm -rf ./c/src/exec/score/cpu/powerpc/wrap
patch -p1 < rtems-rc-19991123-rc-3.diff
Attention:
c/src/exec/score/cpu/[configure.in|aclocal.m4|configure] should be
removed after applying the patch.
|
|
As part of this effort, the mpc750 libcpu code is now shared with the
ppc6xx.
