  • console/console.c, console/uart.c, console/uart.h: implement IOCTLs for the serial (UART) console to install/retrieve a BREAK-IRQ callback. The callback routine (if installed) is invoked from the UART ISR when a BREAK interrupt is detected. This can be used e.g. to enforce a "hotkey" reboot a la vxWorks Ctrl-X (although we use the serial line break condition) NOTE: The callback runs in ISR context.

19        Also turn off mmu/caches for the bootstrap phase, which seems to
20        cause trouble with the 603.  The cpu init functions in the bsp
21        get all that stuff going properly.

50        Per PR216, "libbsp/powerpc/shared" BSP has been modified considerably
51        with the goal to make it more flexible and reusable by other
52        BSPs. The main strategies were:
53            - eliminate hardcoded base addresses; devices use offsets
54              and a BSP defined base address.
55            - separate functionality into different files (e.g. reboot from
56              inch.c to reboot.c) which can be overridden by a 'derived' BSP.
57            - separate initialization code into separate files (e.g.  PCI
58              bridge detection/initialization was separated from the more
59              generic PCI access routines), also to make it easier for
60              'derived' BSPs to substitute their own initialization code.
61        There are also a couple of enhancements and fixes:
62            - IRQ handling code now has a hook for attaching a VME bridge.
63            - OpenPIC is now explicitely initialized (polarities, senses).
64              Eliminated the implicit assumption on the presence of an ISA PIC.
65            - UART and console driver now supports more than 1 port. The current
66              maximum of 2 can easily be extended by enlarging a table (it
67              would even be easier if the ISR API was not broken by design).
68            - fixed polled_io.c so it correctly supports console on COM2
69            - fixed TLB invalidation code (start.S).
70            - exception handler prints a stack backtrace.
71            - added BSP_pciFindDevice() to scan the pci bus for a particular
72              vendor/device/instance.

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