  • console/polled_io.c: libcpu provides 'printk' already. Therefore, the implementation in this file was removed (still used for the bootloader, though). It now provides BSP_output_char() for libcpu's printk().
  • console/uart.c, console/uart.h: BSP_output_char_via_serial() 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).
  • console/console.c, console/consoleIo.h, console/polled_io.c, irq/irq_init.c, openpic/openpic.c, pci/detect_raven_bridge.c: Unfortunately, the supported 'printk' format string subset of the polled-io and libcpu implementations are different - hence, a few format strings in the ppc/shared BSP were changed.
  • Property mode set to 100644

28        BSP code had set the task priority register multiple times of

30        This patch adds openpic_get_source_priority() and
31        openpic_set_source_priority() calls and lets IRQ management code
32        use them.

101        use the serial line break condition) NOTE: The callback runs in

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

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