This patch makes RTEMS/powerpc/shared EABI compliant.

  • irq/irq_init.c, start/Makefile.am, start/start.S, startup/bspstart.c, startup/pgtbl_setup.c, vectors/vectors.h, vectors/vectors_init.c: zero_bss() should clear not only bss but sbss and sbss2 also (this is probably a bugfix, as sbss/sbss2 are probably used even if -msdata=eabi is not specified).
  • start/rtems_crti.S: New file which must be linked immediately after ecrti.o. rtems_crti.o contains a code snippet who lets init() return immediately. Also, a new entry point '_init' to the C++ Ctors is generated for use by the RTEMS Thread_Handler.
  • Property mode set to 100644

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

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

126
127        * startup/linkcmds: In support of gcc 3.1, added one of more
128        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
129        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections
130        and direction of segments to memory regions may also have been
131        addressed.  This was a sweep across all BSPs.
