92        * console/polled_io.c: libcpu provides 'printk' already.
93        Therefore, the implementation in this file was removed (still
94        used for the bootloader, though).  It now provides BSP_output_char()
95        for libcpu's printk().
96        * console/uart.c, console/uart.h: BSP_output_char_via_serial()
97        prototype changed to match the BSP_output_char_function_type.  Note
98        that the motorola BSPs use polled-io for the output_char routine, not
99        the uart.c version. The latter can be used be other BSPs however
100        (e.g. SVGM).

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

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