9        * console/polled_io.c: libcpu provides 'printk' already.
10        Therefore, the implementation in this file was removed (still
11        used for the bootloader, though).  It now provides BSP_output_char()
12        for libcpu's printk().
13        * console/uart.c, console/uart.h: BSP_output_char_via_serial()
14        prototype changed to match the BSP_output_char_function_type.  Note
15        that the motorola BSPs use polled-io for the output_char routine, not
16        the uart.c version. The latter can be used be other BSPs however
17        (e.g. SVGM).
18        * console/console.c, console/consoleIo.h, console/polled_io.c,
19        irq/irq_init.c, openpic/openpic.c, pci/detect_raven_bridge.c:
20        Unfortunately, the supported 'printk' format string subset of the
21        polled-io and libcpu implementations are different - hence, a few
22        format strings in the ppc/shared BSP were changed.

35        This patch adds openpic_get_source_priority() and
36        openpic_set_source_priority() calls and lets IRQ management code
37        use them.

111        callback.  The callback routine (if installed) is invoked from the

113        e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we
114        use the serial line break condition) NOTE: The callback runs in

155        Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably
156        with the goal to make it more flexible and reusable by other
157        BSPs. The main strategies were:
158            - eliminate hardcoded base addresses; devices use offsets
159              and a BSP defined base address.
160            - separate functionality into different files (e.g. reboot from
161              inch.c to reboot.c) which can be overridden by a 'derived' BSP.
162            - separate initialization code into separate files (e.g.  PCI
163              bridge detection/initialization was separated from the more
164              generic PCI access routines), also to make it easier for
165              'derived' BSPs to substitute their own initialization code.
166        There are also a couple of enhancements and fixes:
167            - IRQ handling code now has a hook for attaching a VME bridge.
168            - OpenPIC is now explicitely initialized (polarities, senses).
[85c92574]169              Eliminated the implicit assumption on the presence of an ISA PIC.
170            - UART and console driver now supports more than 1 port. The current
171              maximum of 2 can easily be extended by enlarging a table (it
172              would even be easier if the ISR API was not broken by design).
173            - fixed polled_io.c so it correctly supports console on COM2
174            - fixed TLB invalidation code (start.S).
175            - exception handler prints a stack backtrace.
176            - added BSP_pciFindDevice() to scan the pci bus for a particular
[cd35cf9]177              vendor/device/instance.

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