shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
"libbsp/powerpc/shared" BSP has been modified considerably with the
goal to make it more flexible and reusable by other BSPs. The main
strategies were: - eliminate hardcoded base addresses; devices use
offsets and a BSP defined base address. - separate functionality
into different files (e.g. reboot from inch.c to reboot.c) which can
be overridden by a 'derived' BSP. - separate initialization code
into separate files (e.g. PCI bridge detection/initialization was
separated from the more generic PCI access routines), also to make
it easier for 'derived' BSPs to substitute their own initialization
code. There are also a couple of enhancements and fixes: - IRQ
handling code now has a hook for attaching a VME bridge. - OpenPIC
is now explicitely initialized (polarities, senses). Eliminated the
implicit assumption on the presence of an ISA PIC. - UART and
console driver now supports more than 1 port. The current maximum of
2 can easily be extended by enlarging a table (it would even be
easier if the ISR API was not broken by design). - fixed polled_io.c
so it correctly supports console on COM2 - fixed TLB invalidation
code (start.S). - exception handler prints a stack backtrace. -
added BSP_pciFindDevice() to scan the pci bus for a particular
vendor/device/instance.

* shared/startup/linkcmds: In support of gcc 3.1, added one of more
of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
.gnu.linkonce.sb2.*, and .gnu.linkonce.s.*. Spacing corrections and
direction of segments to memory regions may also have been
addressed. This was a sweep across all BSPs.
2001-04-08 Joel Sherrill <joel@OARcorp.com>
* shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
2001-03-30 Eric Valette <valette@crf.canon.fr>
* shared/Makefile.am, shared/console/consoleIo.h,
shared/include/bsp.h: These modifications are part of the conversion
of the mpc8xx CPU to the "new exception processing model."
* configure.in, motorola_powerpc/Makefile.am,
motorola_powerpc/configure.in: These modifications are in support of
switching the mpc8xx to the use the "new exception processing
model."

* Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
$(RTEMS_TOPdir)/aclocal.
2000-11-01 Joel Sherrill <joel@OARcorp.com>
* shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
and libcsupport.h moved from libc to lib/include/rtems and now must
be referenced as <rtems/XXX.h>. Header file order was cleaned up
while doing this.
2000-10-27 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
GNU canonicalization.
2000-09-29 Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
* shared/startup/linkcmds: Added lines so DWARF debug information
would be available. Otherwise gdb complains that the offsets for
the debug info are incorrect and doesn't load the files.
2000-09-05 Joel Sherrill <joel@OARcorp.com>
* shared/start/start.S: Include proper files to compile.
2000-08-10 Joel Sherrill <joel@OARcorp.com>
* ChangeLog, shared/ChangeLog: New file.
* Makefile.am, motorola_powerpc/Makefile.am, mvme5500/Makefile.am,
mvme5500/start/preload.S, mvme5500/startup/bspstart.c,
shared/startup/bspstart.c: moved linkcmds to shared area for other
BSPs to use
* startup/ldsegs.S: put IDT and GDT into data segment. The CPU modifies
the 'accessed' bit and GDB's (rtems-gdb-stub) text segment checksum
comparison failed...
* libchip/i2c/i2c-2b-eeprom.c, libchip/i2c/i2c-2b-eeprom.h,
libchip/i2c/i2c-ds1621.c, libchip/i2c/i2c-ds1621.h: New files.
* libchip/Makefile.am, libchip/preinstall.am, wrapup/Makefile.am:
added a simple API/library
for i2c devices and drivers for i2c 2-byte eeproms and a ds1621
temperature sensor; API is documented in libi2c.h
* 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
* mvme5500/start/start.S, shared/start/start.S,
shared/startup/bspstart.c: 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)
* 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)
