22        startup/pgtbl_setup.c, vectors/vectors.h, vectors/vectors_init.c:
23        zero_bss() should clear not only bss but sbss and sbss2
24        also (this is probably a bugfix, as sbss/sbss2 are
25        probably used even if -msdata=eabi is not specified).
26        * start/rtems_crti.S: New file which must
27        be linked immediately after ecrti.o. rtems_crti.o contains
28        a code snippet who lets __init() return immediately. Also,
29        a new entry point '_init' to the C++ Ctors is generated
30        for use by the RTEMS Thread_Handler.

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

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

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