77        Therefore, the implementation in this file was removed (still

81        prototype changed to match the BSP_output_char_function_type.  Note
82        that the motorola BSPs use polled-io for the output_char routine, not
83        the uart.c version. The latter can be used be other BSPs however
84        (e.g. SVGM).

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

249        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
250        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections
251        and direction of segments to memory regions may also have been
252        addressed.  This was a sweep across all BSPs.
