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

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

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