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

25        zero_bss() should clear not only bss but sbss and sbss2
26        also (this is probably a bugfix, as sbss/sbss2 are
27        probably used even if -msdata=eabi is not specified).

30        a code snippet who lets __init() return immediately. Also,
31        a new entry point '_init' to the C++ Ctors is generated
32        for use by the RTEMS Thread_Handler.

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

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

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