        * Lots of tinkering and tuning as part of improving interrupt latency

        With these modifications interrupt latency was measured at a worst-case

        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.
        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,

        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.

        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.

2001-03-13      Joel Sherrill <joel@OARcorp.com>

        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs

        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.

        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.

2000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.

2000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
        Switch to GNU canonicalization.

        * This is a major reworking of the mips64orion port to use 
        gcc predefines as much as possible and a big push to multilib
        the mips port.  The mips64orion port was copied/renamed to mips
        to be more like other GNU tools.  Alan did most of the technical
        work of determining how to map old macro names used by the mips64orion
        port to standard compiler macro definitions.  Joel did the merge
        with CVS magic to keep individual file history and did the BSP
        modifications. Details follow:
        * Makefile.am: Made clock and timer subdirectories conditional.
        * configure.in: Ditto.
        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.

2000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * clock/Makefile.am, timer/Makefile.am: Include compile.am
