22        Ethernet driver) would raise machine check exceptions.

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

73        Unfortunately, the supported 'printk' format string subset of the

75        format strings in the ppc/shared BSP were changed.

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

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