4        * bootloader/pci.c: Fixed IO remapping so buses >= 1 are remapped.
5        Reduced PCI space to match bat2.  Fixed incorrect region size
6        calculation in pci_read_bases.  Set PCI latency timers to known
7        sane values.  Changed bridge PCI settings to minimum sane instead
8        of whatever sounded neat in the PCI spec.  Force pf regions to
9        memory mapped to preserve byte access.

13        * bootloader/pci.c: Re-instated code that prevents remapping small
14        IO regions, which if remapped would cause i8259 registers to move
15        out from under the #define'd base addresses.
16        * startup/bspstart.c: Reduced BAT2 PCI memory allocation to 256
17        megs, I incorrectly had extended it which would cause problems with
18        PCI devices that defined prefetchable memory.

27        from the host processor.
28        * motorola/motorola.c, motorola/motorola.h: Added interrupt
29        routing tables in support of FixupPCI.  This is board-specific,
30        each board will have to supply information for FixupPCI() to do
31        anything for it.

34        Existing single hander vectors are undisturbed, a new function
35        added to allow adding/removing handlers from a vector.

57        * console/polled_io.c: libcpu provides 'printk' already.
58        Therefore, the implementation in this file was removed (still
59        used for the bootloader, though).  It now provides BSP_output_char()
60        for libcpu's printk().
61        * console/uart.c, console/uart.h: BSP_output_char_via_serial()
62        prototype changed to match the BSP_output_char_function_type.  Note
63        that the motorola BSPs use polled-io for the output_char routine, not
64        the uart.c version. The latter can be used be other BSPs however
65        (e.g. SVGM).

68        Unfortunately, the supported 'printk' format string subset of the
69        polled-io and libcpu implementations are different - hence, a few
70        format strings in the ppc/shared BSP were changed.

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

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