* shared/interrupts/installisrentries.c: Added support for debug
exception vector.
* shared/interrupts/isr_entries.S: Added support for debug exception
vector.
* 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.
* 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.
* mongoosev/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
* r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.

r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
tx39/include/tx3904.h: All exceptions were given low numbers and thus
can be now be installed and processed in a uniform manner just like interrupts.
Variances between various MIPS ISA levels are not accounted for at this time.

tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
shared maxvectors.c into a variety of CPU model specific versions to simplify
the build process and reduce depdencies. Deleted shared/interrupts/maxvectors.c
and created various CPU model versions.
* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.
* mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
shared/interrupts/maxvectors.c: Now works. Significant rework
of exceptions and interrupt vectoring to clean things up.
* shared/interrupts/vectorexceptions.c: Removed.
* shared/interrupts/Makefile.am: Reflects above.
* shared/interrupts/vectorexceptions.c: New file to decode
exception code and vector appropriate NON-interrupt exception.
* shared/interrupts/Makefile.am: Modified to reflect above.
* mongoosev/duart/mg5uart.c (mg5uart_enable_interrupts): Honor
the other bits set in the Peripheral Function Interrupt Mask
Register when modifying those enabled for the DUART.
* mongoosev/include/mongoose-v.h (MONGOOSEV_ATOMIC_MASK,
MONGOOSEV_PFICR, MONGOOSEV_PFIMR, mongoosev_set_in_pficr,
mongoosev_clear_in_pficr, mongoosev_set_in_pfimr,
mongoosev_clear_in_pfimr, MONGOOSEV_UART_ALL_IRQ_BITS): New macros.
* mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
as he debugged this BSP using a logic analyzer. In particular,
there was a mistake where the index not offset of registers was
in the header file and the baud rate calculation was incorrect.
* tx39/vectorisrs/vectorisrs.c: Modified to have default exception
vector handler. This should be in a separate file so the BSP can
easily override it.
* configure.in: Added new directories.
* shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
when compiling for a TX3904.
* shared/interrupts/maxvectors.c: Corrected conditional logic.
* tx39/Makefile.am: Added vectorisrs.
* tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
* tx39/vectorisrs/.cvsignore: New files. This decodes the
interrupt pending information on the TX3904 and vectors
an interrupt.
* shared/.cvsignore, shared/Makefile.am,
shared/cache/.cvsignore, shared/cache/Makefile.am,
shared/cache/cache.c, shared/cache/cache_.h,

Moved some pieces of interrupt processing from score/cpu to
libcpu/mips since many interrupt servicing characteristics are
CPU model dependent. This patch addresses the number of interrupt
sources and where the ISR prologues are located. The only way to
currently install the ISR prologues requires that the prologues
be installed into RAM.
