97        * console/polled_io.c: libcpu provides 'printk' already.
98        Therefore, the implementation in this file was removed (still
99        used for the bootloader, though).  It now provides BSP_output_char()
100        for libcpu's printk().

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

251        Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably
252        with the goal to make it more flexible and reusable by other
253        BSPs. The main strategies were:
254            - eliminate hardcoded base addresses; devices use offsets
255              and a BSP defined base address.
256            - separate functionality into different files (e.g. reboot from
257              inch.c to reboot.c) which can be overridden by a 'derived' BSP.
258            - separate initialization code into separate files (e.g.  PCI
259              bridge detection/initialization was separated from the more
260              generic PCI access routines), also to make it easier for
261              'derived' BSPs to substitute their own initialization code.
262        There are also a couple of enhancements and fixes:
263            - IRQ handling code now has a hook for attaching a VME bridge.
264            - OpenPIC is now explicitely initialized (polarities, senses).
265              Eliminated the implicit assumption on the presence of an ISA PIC.
266            - UART and console driver now supports more than 1 port. The current
267              maximum of 2 can easily be extended by enlarging a table (it
268              would even be easier if the ISR API was not broken by design).
269            - fixed polled_io.c so it correctly supports console on COM2
270            - fixed TLB invalidation code (start.S).
271            - exception handler prints a stack backtrace.
272            - added BSP_pciFindDevice() to scan the pci bus for a particular
273              vendor/device/instance.

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