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

118        the uart.c version. The latter can be used be other BSPs however

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

284        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,

286        and direction of segments to memory regions may also have been
287        addressed.  This was a sweep across all BSPs.

361        * start/start.S: Increased BAT0 mapping of RAM from 64 meg to
362        256 meg to allow operation on boards with larger RAM sizes.
363        * vectors/vectors_init.c: Modified to call 'generic' powerpc
364        vector function (mpc60x_vector_is_valid) instead of MPC750
365        specific function to allow operation on boards with CPUs other
366        than the MPC750.

370        * Makefile.am, console/consoleIo.h, include/bsp.h:
371        These modifications are part of the conversion of the
372        mpc8xx CPU to the "new exception processing model."

375
376        * startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
377        and libcsupport.h moved from libc to lib/include/rtems and
378        now must be referenced as <rtems/XXX.h>.   Header file order
379        was cleaned up while doing this.

382
383        * startup/linkcmds: Added lines so DWARF debug information
384        would be available.  Otherwise gdb complains that the offsets
385        for the debug info are incorrect and doesn't load the files.
