        Therefore, the implementation in this file was removed (still
        used for the bootloader, though).  It now provides BSP_output_char()
        for libcpu's printk().

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

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

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