12        This patch reverts enabling MCP interrupts for the motorola_powerpc
13        BSPs. REASON: pci config space scanning (as e.g. done by the DEC
14        Ethernet driver) would raise machine check exceptions.

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

65        Unfortunately, the supported 'printk' format string subset of the
66        polled-io and libcpu implementations are different - hence, a few
67        format strings in the ppc/shared BSP were changed.

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

218        * startup/linkcmds: In support of gcc 3.1, added one of more
219        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
220        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections
221        and direction of segments to memory regions may also have been
222        addressed.  This was a sweep across all BSPs.
