* cdl/xxxx.cdl:
Changed values for CYGNUM_HAL_RTC_NUMERATOR,
CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
"default_value" from "calculated". This makes it easier
to change these values globally.

| 42 | |
| 43 * include/halboot.si: Add a dummy LED macro for debug in the | |
| 44 vectors.S; correct a scary line length. | |

| 53 that they can co-exist in an eCos build tree (PR 19184) | |
| 54 * include/pkgconf/*.mlt: give all MLT files unique names so | |

| 59 These log entries from 1999-02-22 to 1999-02-24 were executed in | |
| 60 a branch; this change is a merge of that branch into the trunk. | |
| 61 | |
| 62 (1999-02-23 John Dallaway <jld@cygnus.co.uk>) | |
| 63 | |
| 64 * include/pkgconf/hal_sparclite_sim.h: New rules | |
| 65 CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_GDB | |
| 66 CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_SERIAL_RS232_COMMON | |
| 67 | |
| 68 (1999-02-22 Hugo Tyson <hmt@cygnus.co.uk>) | |
| 69 | |
| 70 * src/hal_priv.c (hal_board_prestart, hal_board_poststart): | |
| 71 Shut down the erc32 watchdog in and enable interrupts in these two | |
| 72 new routines. | |
| 73 | |
| 74 * include/halboot.si: | |
| 75 Remove N/A code that I was just storing here, and install the real | |
| 76 vector instructions in this fragment; there be cache-wangling to | |
| 77 do in hardware cases either side of the vector installation. | |
| 78 | |
| 79 1999-02-20 Jonathan Larmour <jlarmour@cygnus.co.uk> | |

| 85 Add a FIX ME | |
| 86 | |
| 87 1999-02-08 John Dallaway <jld@cygnus.co.uk> | |
| 88 | |
| 89 * src/sim.ld: Remove platform-specific linker script for | |
| 90 MLT compliance. | |
| 91 | |
| 92 * src/PKGconf.mak: Remove build rules for sim.ld. | |
| 93 | |
| 94 * include/pkgconf/ram.*: Add MLT save file and and linker | |
| 95 script fragment for RAM startup. | |
| 96 | |
| 97 1999-02-01 Hugo Tyson <hmt@cygnus.co.uk> | |
| 98 | |
| 99 * include/halboot.si: | |
| 100 New file: performs platform-oriented setup of RAM and cache | |
| 101 controllers, and quietens any interrupt sources. | |
| 102 | |
| 103 * include/pkgconf/hal_sparclite_sim.h: | |
| 104 Correct comments/CDL description of sim invocation. | |
| 105 | |
| 106 1999-01-28 Hugo Tyson <hmt@cygnus.co.uk> | |
| 107 | |
| 108 * include/hal_cache.h: NEW FILE to this directory; moved here from | |
| 109 the sparclite/arch tree; cache control is very much board-specific | |
| 110 | |
| 111 * include/hal_clock.h: NEW FILE to this directory; it was a part | |
| 112 of hal_intr.h, but is now here because the clock is target determined. | |
| 113 | |
| 114 * include/hal_xpic.h: NEW FILE to this directory; it was a part of | |
| 115 hal_intr.h, but is now here because the detail of interrupot | |
| 116 control is target determined. | |
| 117 | |
| 118 * src/hal_priv.c: NEW FILE to this directory; it was a part | |
| 119 of hal_intr.h, but is now here because the clock is target | |
| 120 determined, and it's the clock that needs a local variable. | |
| 121 | |
| 122 * src/PKGconf.mak (COMPILE): compile it. | |
| 123 | |
| 124 | |
| 125 1999-01-26 Hugo Tyson <hmt@cygnus.co.uk> | |
| 126 | |
| 127 * src/sim.ld: | |
| 128 Add copyright notice. (Though these files will later be generated | |
| 129 by a tool and so not copyright, these default setups are.) | |
| 130 | |
| 131 1999-01-22 Hugo Tyson <hmt@cygnus.co.uk> | |
| 132 | |
| 133 * src/sim.ld: | |
| 134 Remove some bogus comments. | |
| 135 | |
| 136 1999-01-21 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 137 | |
| 138 * src/sim.ld: | |
| 139 Remove all traces of non-CYG_KERNEL_USE_INIT_PRIORITY code | |
| 140 | |
| 141 1999-01-21 Hugo Tyson <hmt@cygnus.co.uk> | |
| 142 | |
| 143 * src/sim.ld: | |
| 144 Align bss and rom/ram_data starts and ends by 8 bytes to permit | |
| 145 fast copy routines. | |
| 146 | |
| 147 1999-01-19 Hugo Tyson <hmt@cygnus.co.uk> | |
| 148 | |
| 149 Modified files in arch: | |
| 150 * include/hal_arch.h | |
| 151 * include/hal_intr.h | |
| 152 * src/PKGconf.mak | |
| 153 * src/context.S | |
| 154 * src/hal_intr.c | |
| 155 * src/vec_ivsr.S | |
| 156 * src/vec_xvsr.S | |
| 157 * src/vectors.S | |
| 158 | |
| 159 New files in arch: | |
| 160 * src/hal_boot.c (bss initialization, constructors &c) | |
| 161 * include/hal_cache.h (empty but required header) | |
| 162 | |
| 163 Modified files in sim: | |
| 164 * include/hal_diag.h | |
| 165 | |
| 166 Lots more progress; essentially, everything now works. | |
| 167 | |
| 168 Simulator's treatment of stdio is poor though, it doesn't work | |
| 169 under pkgtest. This has been slowing me up. | |
| 170 | |
| 171 1999-01-14 Hugo Tyson <hmt@cygnus.co.uk> | |
| 172 | |
| 173 * ecc/ecc/hal/sparclite/...: | |
| 174 | |
| 175 Initial checkin of SPARClite HAL; it doesn't work yet, except the | |
| 176 most trivial of tests - timer and interrupt manipulation stuff is | |
| 177 entirely absent. | |
| 178 | |
| 179 Here's some documentation of the initial checkin tree; this will | |
| 180 change, as platform dependent stuff moves correctly into the sim | |
| 181 or <board> directories. | |
| 182 | |
| 183 arch/current/include: | |
| 184 basetype.h nothing much here. | |
| 185 vectors.h definitions of symbols shared between the | |
| 186 various vector code assembler files, can be | |
| 187 included in both C and assembler. | |
| 188 hal_intr.h various macros for clock and interrupt | |
| 189 control plus the eCos vector numbering scheme; we | |
| 190 map thus: | |
| 191 what SPARC trap type eCos vector numbers | |
| 192 ----------------------------------------------- | |
| 193 (not used) --- 0 | |
| 194 interrupts (17-31) 1-15 | |
| 195 user traps (128-255) 16 | |
| 196 exceptions (1-9,36==4) 17-25 | |
| 197 others (10,?) 26 | |
| 198 ----------------------------------------------- | |
| 199 Trap types 5 and 6 which would be eCos vectors 21 | |
| 200 and 22 are handled in the trampoline code in | |
| 201 file src/vectors.S | |
| 202 hal_arch.h definition of a thread context, plus | |
| 203 macros for thread switching and the like. Some | |
| 204 ancillary bit twiddling macros and cache barriers | |
| 205 too. | |
| 206 | |
| 207 arch/current/include/pkgconf: | |
| 208 hal_sparclite.h pkgconf config/header file. | |
| 209 | |
| 210 arch/current/src: | |
| 211 vectors.S boot-up stuff, trampoline code that hangs | |
| 212 on the interrupt/trap vector, handlers for window | |
| 213 under/overflow. Saves some state in registers | |
| 214 then jumps to the interrupt or exception VSR | |
| 215 respectively. | |
| 216 Also instantiates the VSR table. | |
| 217 vec_ivsr.S the default interrupt VSR; it establishes | |
| 218 a C calling environment (ie. anticipates a window | |
| 219 overflow) then locks the scheduler, calls the ISR | |
| 220 with appropriate arguments, and then interrupt_end() | |
| 221 before undoing that environment, anticipating | |
| 222 window underflow and returning to the interrupted | |
| 223 instruction. | |
| 224 vec_xvsr.S the default exception AKA trap VSR; does | |
| 225 the same as the interrupt one but without the | |
| 226 scheduler lock or interrupt end. | |
| 227 hal_intr.c instantiates the ISR table used by the | |
| 228 code above. | |
| 229 context.S context switch code, saves and loads up a | |
| 230 whole register state, coroutine or longjump-like. | |
| 231 icontext.c initializes a context to "jump" to in | |
| 232 context.S at the birth of a new thread. | |
| 233 | |
| 234 sim/current/include: | |
| 235 hal_diag.h macros to deal with debugging output via a | |
| 236 fake serial device of some kind; initially empty, | |
| 237 but definitely board/sim dependent. | |
| 238 | |
| 239 sim/current/include/pkgconf: | |
| 240 hal_sparclite_sim.h pkgconf config/header file. | |
| 241 | |
| 242 sim/current/src: | |
| 243 sim.ld linker script bits for "sim" target. | |
