* Merged r46kstub.c into RTEMS distribution without modification.
I got the code from Franz Fischer <Franz.Fischer@franz-fischer.de>
who had used this with an old version of RTEMS with the mips64orion
port of RTEMS. After adding this to the repository, I will tailor
this to work with the RTEMS exception processing model and trim
no longer needed parts.
* ChangeLog, gdb_if.h, ioaddr.h, limits.h, Makefile, mips_opcode.h,
r4600.h, r46kstub.c, r46kstub.ld, README, stubinit.S:
* mkbinutilspec.in, mkgccnewlibspec.in, gccnewlib/base-chill.add,
gccnewlib/base-g77.add, gccnewlib/base-gcc.add,
gccnewlib/base-gcj.add, gccnewlib/gccnewlib.add,
gccnewlib/target-chill.add, gccnewlib/target-g77.add,
gccnewlib/target-gcc.add, gccnewlib/target-gcj.add,
gccnewlib/target-objc.add: Added more support for Canadian Cross
building.
* isr_entries.S: Removed comment incorrectly indicating this
file was cpu_asm.S.
* vectorexceptions.c (mips_dump_exception_frame): New routine
broken out from default exception handler.
* cpu_asm.S: Enhanced to save/restore more registers on
exceptions.
* rtems/score/cpu.h (CPU_Interrupt_frame): Enhanced to list every
register individually and document when it is saved.
* idtcpu.h: Added constants for the coprocessor 1 registers
revision and status.
* include/lr33000.h, include/lr330x0.h, include/r3000.h, start/mg5.h:
New files missed in previous commit.
* timer/timer.c: Use rtems/bspIo.h not just bspIo.h.
* So many patches have been posted recently on the mailing list and
because we were unable to find correct solution to compile on various
linux distros (due to rpcgen incompatibilities), and because the coding
style of rdbg was rather inconsistant among various pieces of code, I
decided to:
1) make some cleaning regarding global coding style (using
indent + manual edits),
2) incorporate/review the paches send by various people
(S. Holford, T. Strauman),
3) Fix the bug due to varying rpcgen code generation
in remdeb_svc.c,
4) Remove some dead code,
5) Apply a patches enabling to call enterRdbg imediately
after rdbg initialization is done,
NB : the paches is huge but it is mainly due to coding styke chnages.
Only few lines of codes have been really changed and they do not impact
rdbg functionnality (AFAIKT).

New files missed in previous commit.
* timer/timer.c: Use rtems/bspIo.h not just bspIo.h.
* rtems.ads, rtems.adb: Formatting cleaned up. Task based timer
directives added. This is Timer_Initiate_Server,
Timer_Server_Fire_After, and Timer_Server_Fire_When.

* pppd/rtemspppd.c (rtems_pppd_disconnect): Modified to avoid bringing
the link down too fast.
NOTE: Mike reports successfully running at 56K baud on a direct link.
* Update of BSP to address problems restarting, provide more
information during boot, and better handle ROM vs RAM images.
* README, include/bsp.h, start/regs.S, start/start.S,
startup/bspstart.c, startup/linkcmds, timer/timer.c: Updated
* Lots of tinkering and tuning as part of improving interrupt latency
and improving the per-task interrupt level control and FP mask handling.
With these modifications interrupt latency was measured at a worst-case
of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
RTEMS tasks in the application.
* mongoosev/README: Updated.
* mongoosev/include/mongoose-v.h: Masks modified.
* mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
software prioritization of interrupts. If a higher priority interrupt
occurs while we are looking for new interrupts, we will reinitiate the
scan of all interrupts.
* shared/interrupts/vectorexceptions.c: Removed warning and deleted
blank lines.
* cpu.c: Enhancements and fixes for modifying the SR when changing
the interrupt level.
* cpu_asm.S: Fixed handling of FP enable bit so it is properly
managed on a per-task basis, improved handling of interrupt levels,
and made deferred FP contexts work on the MIPS.
* rtems/score/cpu.h: Modified to support above changes.
* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.
Mike did significant testing and reports that it seems to be
more stable and handle larger packets better. This patch
replaces the termios tasks with more general pppd network
driver tasks. The functions pppinput() and pppstart() get
called from the interrupt service routine.
* libc/termios.c: Added PPCDISC.
* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.

* Fixed bug where resetting a timer that was not at the head
of one of the task timer chains resulted in the Timer Server
task waking up too far in the future.
* Added rtems_timer_get_information() directive to support testing.
* sp31/init.c, sp31/system.h, sp31/task1.c: Modified to test for
above condition.
