2002-02-27      Greg Menke <gregory.menke@gsfc.nasa.gov>

        * mongoosev/include/mongoose-v.h: Added cache constants.
        * mongoosev/vectorisrs/vectorisrs.c: More tinkering to improve
        performance.

2002-02-08      Joel Sherrill <joel@OARcorp.com>

        * mongoosev/vectorisrs/vectorisrs.c: Fixed to use new frame format.

2001-02-05      Joel Sherrill <joel@OARcorp.com>

        * 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.

2001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>

        * mongoosev/vectorisrs/vectorisrs.c,
        shared/interrupts/vectorexceptions.c: Use rtems/bspIo.h, not just
        bspIo.h.

2001-02-01      Greg Menke <gregory.menke@gsfc.nasa.gov>

        * 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.

2002-01-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * mongoosev/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
        * r46xx/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.
        * shared/interrupts/vectorexceptions.c: Include rtems/bspIo.h instead of bspIo.h.
        * tx39/vectorisrs/vectorisrs.c: Include rtems/bspIo.h instead of bspIo.h.

2001-10-11      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * .cvsignore: Add autom4te.cache for autoconf > 2.52.
        * configure.in: Remove.
        * configure.ac: New file, generated from configure.in by autoupdate.

2001-09-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * tx39/include/Makefile.am: Use 'TMPINSTALL_FILES ='.
        * mongoosev/include/Makefile.am: Use 'TMPINSTALL_FILES ='.
        * mongoosev/duart/Makefile.am: Use 'PREINSTALL_FILES ='.
        * shared/cache/Makefile.am: Use 'PREINSTALL_FILES ='.
        * shared/cache/Makefile.am: Use 'CLEANFILES ='.

2000-05-24      Joel Sherrill <joel@OARcorp.com>

        * mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
        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.
        * mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
        r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
        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.

2001-05-24      Greg Menke <gregory.menke@gsfc.nasa.gov>

        * clock/clock.S: Move placement of nop.

2001-05-22      Greg Menke <gregory.menke@gsfc.nasa.gov>

        * 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,

        of exceptions and interrupt vectoring to clean things up.
        * shared/interrupts/vectorexceptions.c: Removed.

2001-05-07      Joel Sherrill <joel@OARcorp.com>

        * shared/interrupts/vectorexceptions.c: New file to decode
        exception code and vector appropriate NON-interrupt exception.  
        * shared/interrupts/Makefile.am: Modified to reflect above.

2001-04-20      Joel Sherrill <joel@OARcorp.com>

        * 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.

2001-04-16      Joel Sherrill <joel@OARcorp.com>

        * 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.

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

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

        New files.
        * Makefile.am, configure.in, shared/interrupts/Makefile.am,
        shared/interrupts/maxvectors.c: Added support for mongoosev.
        * tx39/vectorisrs/vectorisrs.c: Corrected warning.

2001-03-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * shared/cache/Makefile.am, tx39/include/Makefile.am:
        Apply include_*HEADERS instead of H_FILES.

2001-01-08      Joel Sherrill <joel@OARcorp.com>

        * Added r46xx directory.
        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
        * shared/interrupts/installisrentries.c: Fixed typo.

2000-12-19      Joel Sherrill <joel@OARcorp.com>

        * 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.

2000-12-13      Joel Sherrill <joel@OARcorp.com>

        * 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.

2000-12-13      Joel Sherrill <joel@OARcorp.com>

        * shared/.cvsignore, shared/Makefile.am,
        shared/cache/.cvsignore, shared/cache/Makefile.am,

        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
        shared/interrupts/installisrentries.c,
        shared/interrupts/isr_entries.S,
        shared/interrupts/maxvectors.c, tx39/.cvsignore,
        tx39/Makefile.am, tx39/include/.cvsignore,
        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
        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.

2000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * 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.

2000-10-24      Alan Cudmore <alanc@linuxstart.com> and
        Joel Sherrill <joel@OARcorp.com>

        * 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

2000-08-10      Joel Sherrill <joel@OARcorp.com>

        * ChangeLog: New file.
