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.

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.

* console/console.c: Removed __assert() which conflicts with newlib.

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.

As part of this effort, the mpc750 libcpu code is now shared with the
ppc6xx.
