  • 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.

30
31        * shared/interrupts/vectorexceptions.c: New file to decode

46
47        * mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h
48        Modifications made with Gregory Menke <gregory.menke@gsfc.nasa.gov>
49        as he debugged this BSP using a logic analyzer.  In particular,
50        there was a mistake where the index not offset of registers was
51        in the header file and the baud rate calculation was incorrect.
52
532001-03-13      Joel Sherrill <joel@OARcorp.com>
54
55        * Added mongoose-v, mongoose-v/include, and mongoose-v/vectorisrs
56        directories.
57        * mongoosev/.cvsignore, mongoosev/Makefile.am, mongoosev/README,
58        mongoosev/duart/.cvsignore, mongoosev/duart/Makefile.am,
59        mongoosev/duart/README.mguart, mongoosev/duart/mg5uart.c,

70
71        * shared/cache/Makefile.am, tx39/include/Makefile.am:
72        Apply include_*HEADERS instead of H_FILES.
73
742001-01-08      Joel Sherrill <joel@OARcorp.com>
75
76        * Added r46xx directory.
77        * Makefile.am, configure.in: Modified to reflect addition of r46xx.
78        * shared/interrupts/installisrentries.c: Fixed typo.

81        r46xx/vectorisrs/vectorisrs.c: New files.
82
832000-12-19      Joel Sherrill <joel@OARcorp.com>
84
85        * tx39/vectorisrs/vectorisrs.c: Modified to have default exception
86        vector handler.  This should be in a separate file so the BSP can
87        easily override it.
88
892000-12-13      Joel Sherrill <joel@OARcorp.com>
90
91        * configure.in: Added new directories.
92        * shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39
93        when compiling for a TX3904.
94        * shared/interrupts/maxvectors.c: Corrected conditional logic.
95        * tx39/Makefile.am: Added vectorisrs.
96        * tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
97        * tx39/vectorisrs/.cvsignore: New files.  This decodes the
98        interrupt pending information on the TX3904 and vectors
99        an interrupt.

1012000-12-13      Joel Sherrill <joel@OARcorp.com>
102
103        * shared/.cvsignore, shared/Makefile.am,
104        shared/cache/.cvsignore, shared/cache/Makefile.am,
105        shared/cache/cache.c, shared/cache/cache_.h,
106        shared/interrupts/.cvsignore, shared/interrupts/Makefile.am,
107        shared/interrupts/installisrentries.c,
108        shared/interrupts/isr_entries.S,
109        shared/interrupts/maxvectors.c, tx39/.cvsignore,
110        tx39/Makefile.am, tx39/include/.cvsignore,
111        tx39/include/Makefile.am, tx39/include/tx3904.h: New file.
112        Moved some pieces of interrupt processing from score/cpu to
113        libcpu/mips since many interrupt servicing characteristics are
114        CPU model dependent.  This patch addresses the number of interrupt
115        sources and where the ISR prologues are located.  The only way to
116        currently install the ISR prologues requires that the prologues
117        be installed into RAM.
118
1192000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
120
121        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
122
1232000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
124
125        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
126
1272000-10-26      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
128
129        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
130        Switch to GNU canonicalization.
131
1322000-10-24      Alan Cudmore <alanc@linuxstart.com> and
133        Joel Sherrill <joel@OARcorp.com>
134
135        * This is a major reworking of the mips64orion port to use
136        gcc predefines as much as possible and a big push to multilib
137        the mips port.  The mips64orion port was copied/renamed to mips
138        to be more like other GNU tools.  Alan did most of the technical
139        work of determining how to map old macro names used by the mips64orion
140        port to standard compiler macro definitions.  Joel did the merge
141        with CVS magic to keep individual file history and did the BSP
142        modifications. Details follow:
143        * Makefile.am: Made clock and timer subdirectories conditional.
144        * configure.in: Ditto.
145        * clock/clock.S: Switch from using <idtmon.h> to <asm.h>.
146        * clock/gettime.S: Switch from using <idtmon.h> to <asm.h>.
147
1482000-09-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
149
150        * clock/Makefile.am, timer/Makefile.am: Include compile.am
151

153
154        * ChangeLog: New file.
