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

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

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