PR 833/bsps
* irq/irq_asm.S: Currently, all (new exception) BSPs explicitely enable
the FPU across the user ISR but DONT save/restore the FPU context.
Any use of the FPU fron the user handler (e.g., due to GCC
optimizations) result in corruption. The fix results in an exception
in such cases (user ISR must explicitely save/enable/restore FPU).

hardware, replacing it with sfree which deletes the memory region
from the setup code, leaving it disabled.

IO regions, which if remapped would cause i8259 registers to move

PR 379/bsps
* console/polled_io.c: libcpu provides 'printk' already.
Therefore, the implementation in this file was removed (still
used for the bootloader, though). It now provides BSP_output_char()
for libcpu's printk().
* console/uart.c, console/uart.h: BSP_output_char_via_serial()
prototype changed to match the BSP_output_char_function_type. Note
that the motorola BSPs use polled-io for the output_char routine, not
the uart.c version. The latter can be used be other BSPs however
(e.g. SVGM).

irq/irq_init.c, openpic/openpic.c, pci/detect_raven_bridge.c:
Unfortunately, the supported 'printk' format string subset of the
polled-io and libcpu implementations are different - hence, a few
format strings in the ppc/shared BSP were changed.

* irq/irq.c, irq/irq_init.c, openpic/openpic.c, openpic/openpic.h:
BSP code had set the task priority register multiple times of

startup/pgtbl_setup.c, vectors/vectors.h, vectors/vectors_init.c:
zero_bss() should clear not only bss but sbss and sbss2
also (this is probably a bugfix, as sbss/sbss2 are
probably used even if -msdata=eabi is not specified).
* start/rtems_crti.S: New file which must
be linked immediately after ecrti.o. rtems_crti.o contains
a code snippet who lets __init() return immediately. Also,
a new entry point '_init' to the C++ Ctors is generated
for use by the RTEMS Thread_Handler.

- avoid a name clash by renaming 'vsprintf' & friends
to 'k_vsprintf' etc.
- let 'rtemsReboot' print a stack trace (in case an 'assert' failed)
- irq.c:
* fix: remove implicit assumption that ISA interrupt vectors start
at 0
* add BSP hook to let a VME interrupt acknowledge the PCI/openpic
IRQ. (SEE ALSO THE ppc-sharedbsp-vme.diff patch)
- fix: EABI compliance; isr/exception lowlevel handlers must not
clobber R2 or R13
- fix: openpic_init was called with the polarity/senses tables
swapped (fixed wrong order of arguments)

PR 349/bsps
* console/console.c, console/uart.c, console/uart.h: implement
IOCTLs for the serial (UART) console to install/retrieve a BREAK-IRQ
callback. The callback routine (if installed) is invoked from the
UART ISR when a BREAK interrupt is detected. This can be used
e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we
use the serial line break condition) NOTE: The callback runs in
ISR context.

Also turn off mmu/caches for the bootstrap phase, which seems to
cause trouble with the 603. The cpu init functions in the bsp
get all that stuff going properly.

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.
2001-05-09 Joel Sherrill <joel@OARcorp.com>
* 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.
