* irq/irq_asm.S, startup/bspstart.c: _ISR_Nest_level is now properly
maintained and any BSP which does not do so will trip a panic in the
shared code.

* pci/detect_raven_bridge.c, startup/bspstart.c:
This patch reverts enabling MCP interrupts for the motorola_powerpc
BSPs. REASON: pci config space scanning (as e.g. done by the DEC
Ethernet driver) would raise machine check exceptions.

* network/elnk.c: Due to a bug in the driver, if multiple packets
are queued onto an elnk board, the ISR will deadlock the device with
a tx complete interrupt. Lighter tx loads are not affected as they
end up submitting single packets to the device.

PR 432/bsps
* bootloader/pci.c: Re-instated code that prevents remapping small
IO regions, which if remapped would cause i8259 registers to move
out from under the #define'd base addresses.
* startup/bspstart.c: Reduced BAT2 PCI memory allocation to 256
megs, I incorrectly had extended it which would cause problems with
PCI devices that defined prefetchable memory.
PR 433/tools
* mips-stub.c: Patch from C. M. Heard <heard@pobox.com> described as:
The purpose of the patch is to make the stub ignore all
characters except '+' (ack) or '-' (nak) when it has transmitted a
packet and expects an acknowledgment. Without the patch,
putpacket() will retransmit each time it receives anything other
than '+' when expecting an ack, and that, bitter experience has
found, frequently results in the stub failing to sync up when
initially attaching to gdb.
I think that rtems users will notice significant improvement in
the of the mips stub if this patch is incorporated in the
distribution; certainly I did in my stand-aline environment. I
should hasten to add that it is only an improvement and not a 100%
cure for synchronization problems because '+' characters can (and
do) during as message data, and it's still possible for these to
be mistaken as acks. I have no idea how to fix that short of
redesigning the gdb-remote protocol.

* ppc403/ictrl/ictrl.c (ictrl_isr): We acknolwegde the interrupt in
interrupt controller (clr_exisr(mask)) before calling the interrupt
handler that will acnowledge the interrupt source. This results in
the interrupt beeing seen a second time by the interrupt controller.

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).
* console/console.c, console/consoleIo.h, console/polled_io.c,
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.
