9        * irq/irq.c, irq/irq_init.c, openpic/openpic.c, openpic/openpic.h:
10        BSP code had set the task priority register multiple times of
11        the OpenPIC instead of setting the individual source priorities.
12        This patch adds openpic_get_source_priority() and
13        openpic_set_source_priority() calls and lets IRQ management code
14        use them.

36        a new entry point '_init' to the C++ Ctors is generated
37        for use by the RTEMS Thread_Handler.

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

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

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