2003-04-10  Nick Garnett  
2
 
3
        * src/sh.ld:
4
        Added entry for .stack section in data section.
5
 
6
2003-01-31  Mark Salter  
7
 
8
        * src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
9
        handle exit.
10
 
11
2002-08-02  Andrew Lunn 
12
 
13
        * cdl/hal_sh.cdl: The Redboot exec command can now be
14
          disabled by CDL
15
 
16
2002-04-30  Jesper Skov  
17
 
18
        * include/hal_var_sp.inc: Allow variant to provide custom
19
        interrupt vector layout. This means the size of
20
        hal_interrupt_handlers/objects/data can be reduced if the vector
21
        layout is sparse. Something similar could be done for
22
        _HW_EXEC_ENTRY_TABLE, saving exception_vector_int entries in the
23
        $vectors_code block. However, this code usually resides in flash
24
        so there's not much point given todays flash block sizes.
25
 
26
        * cdl/hal_sh.cdl: Added CYGHWR_HAL_SH_FPU and
27
        CYGHWR_HAL_SH_NO_FPU, allowing an arch level control of FPU
28
        related tests.
29
        Skipping test handled in a different way now, so the implements
30
        statement has been deleted again.
31
 
32
2002-04-29  Jesper Skov  
33
 
34
        * include/hal_var_bank.inc: Define hal_exception_entry_extras and
35
        hal_interrupt_entry_extras.
36
        * include/hal_var_sp.inc: Define hal_exception_entry_extras and
37
        hal_interrupt_entry_extras. Disable interrupts on exception
38
        entry.
39
        * src/vectors.S: Call hal_exception_entry_extras and
40
        hal_interrupt_entry_extras.
41
 
42
2002-04-29  Jonathan Larmour  
43
 
44
        * src/vectors.S:
45
        Don't use .file as it can confuse debugging since the .file
46
        doesn't contain the path and therefore the debugger will never
47
        know where it lives! This conflicts with using -Wa,--gstabs.
48
 
49
2002-04-15  Jonathan Larmour  
50
 
51
        * src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
52
        __do_syscall.
53
 
54
2002-04-22  Jesper Skov  
55
 
56
        * include/hal_var_sp.inc: 7044 needs different vector layout than
57
        76xx since its vectors are hardwired.
58
 
59
2002-04-18  Jesper Skov  
60
 
61
        * include/hal_var_sp.inc: Do no translation of entry address if
62
        cache module defines CYGARC_SH_MOD_CAC_NO_WINDOWS.
63
 
64
        * include/hal_intr_vecs.h: Move all vectors after IRQ7 to variant
65
        header. Define _IRQ and _LVL for all of the first 7
66
        interrupts. Define CYGNUM_HAL_INTERRUPT_LVL_MAX
67
 
68
2002-03-06  Jesper Skov  
69
 
70
        * include/hal_var_sp.inc: Fix asm comments.
71
 
72
2002-02-28  Jesper Skov  
73
 
74
        * src/hal_syscall.c (hal_syscall_handler): Added.
75
        * src/sh_stub.c (__is_bsp_syscall): Added.
76
        * cdl/hal_sh.cdl: Build hal_syscall.c
77
 
78
2002-02-27  Jesper Skov  
79
 
80
        * src/sh_stub.c (__computeSignal): Changed to use DATA_ACCESS
81
        names as well.
82
        * include/hal_intr_vecs.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,
83
        _CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Same.
84
 
85
2002-02-26  Jesper Skov  
86
 
87
        * include/hal_intr_vecs.h: Use DATA_ACCESS vector names instead of
88
        ADDRESS_ERROR names.
89
 
90
2002-02-15  Jesper Skov  
91
 
92
        * src/sh_stub.c (__single_step): Use normal breakpoint instruction
93
        (trapa #32) for single-stepping.
94
        On the SH2 the use of trapa#255 causes a different (and unhandled)
95
        exception, in the range reserved for application
96
        exceptions/interrupts.
97
 
98
2002-02-14  Jesper Skov  
99
 
100
        * include/hal_var_bank.h: Switch mach/macl entries.

        * include/hal_var_sp.h: Same.
102
 
103
        * include/hal_var_sp.inc: Reserve (additional) trampoline for NMI
104
        to make eCos interrupt numbers match. Make traps use trap numbers
105
        32-64.
106
        (hal_cpu_save_regs): Remember to adjust SP for R0 save location.
107
        (hal_cpu_restore_regs_return): Rewritten to fix errors and allow
108
        SP to be changed from GDB.
109
 
110
2002-02-13  Jesper Skov  
111
 
112
        * src/context.S (hal_thread_load_context): Load up stack pointer
113
        before enabling interrupts.
114
 
115
        * include/hal_var_sp.inc: Fetch the VSR pointer and jump to it
116
        instead of into the VSR table.
117
        (hal_cpu_restore_regs_return): adjust sp to point to exception
118
        state before returning.
119
 
120
2002-02-08  Jesper Skov  
121
 
122
        * src/vectors.S: tweak ROMRAM relocation code.
123
 
124
2002-02-07  Jesper Skov  
125
 
126
        * include/hal_var_sp.inc: Moved _reset code to below vectors.
127
 
128
2002-01-17  Jesper Skov  
129
 
130
        * include/hal_var_bank.inc: Include SH3 register references. Make
131
        better use of some delay slots.
132
 
133
        * src/vectors.S: Don't save exception/interrupt state on stack
134
        with debug markers. Load up event value in R4 before calling
135
        hal_intc_decode so it can be a nop if desired. Removed some SH3
136
        register references.
137
 
138
        * include/hal_var_sp.inc: Include SH2 offsets, export
139
        _HW_EXC_ENTRY_TABLE, fix some typos.
140
 
141
        * include/hal_intr_vecs.h: IRL vectors renamed. Added IRQ
142
        vectors.
143
 
144
2002-01-16  Jesper Skov  
145
 
146
        * include/hal_var_bank.h: Fix typo.
147
 
148
        * src/sh_stub.c (__computeSignal): Only handle defined vectors.
149
 
150
        * include/hal_intr_vecs.h: Decode NMI as interrupt 0, moved all
151
        other vectors. Provide MEM_FAULT vector range.
152
        * include/hal_var_sp.inc: Changes for NMI-as-interrupt-0.
153
        * include/hal_var_sp.h: Renamed vector to event to share code.
154
 
155
        * include/hal_intr_excevt.h: Added MEM_FAULT vector ranges and
156
        CYGHWR_SH_RTC_TIMER_IS_TMU.
157
        * src/hal_misc.c (hal_delay_us): Only build if
158
        CYGHWR_SH_RTC_TIMER_IS_TMU. Use MEM_FAULT vector range.
159
 
160
        * include/hal_intr.h: Deleted clock controls.
161
 
162
        * cdl/hal_sh.cdl: Use CYGNUM_HAL_RTC_PRESCALE instread of
163
        module-specific prescale variable.
164
 
165
        * include/hal_intr_excevt.h (_CYGNUM_HAL_VECTOR_FIRST_MEM_FAULT,
166
        _CYGNUM_HAL_VECTOR_LAST_MEM_FAULT): Define.

        * src/hal_misc.c (cyg_hal_exception_handler): Use new _MEM_FAULT
169
        vector range.
170
 
171
 
172
        * include/hal_intr_vecs.h: Removed RTC code.
173
 
174
        * include/hal_arch.h: Changed breakpoint instruction to match that
175
        used in GDB 5.1.
176
        It also makes better sense on the SH2.
177
 
178
        * include/hal_intr_excevt.h: Interrupt/exception vectors and clock
179
        handling code moved here...
180
        * include/hal_intr.h: From here.
181
        * include/hal_intr_vecs.h: Interrupt/exception vector layout +
182
        clock handling for SH1/SH2 variants.
183
 
184
        * include/hal_var_sp.inc: Added some comments, fixed number of
185
        pre-VSR vectors, renamed HW_VSR_TABLE to HW_EXC_ENTRY_TABLE to
186
        avoid confusion (it has nothing to do with eCos VSRs). Finally,
187
        made the pre-VSR stuff only compile when really required (since
188
        it's 4KiB).
189
 
190
2002-01-14  Jesper Skov  
191
 
192
        * include/hal_arch.h: Moved HAL_SavedRegisters structure to
193
        bank variant headers. Same with HAL_THREAD_INIT_CONTEXT,
194
        HAL_THREAD_GET_SAVED_REGISTERS, HAL_GET_GDB_REGISTERS,
195
        HAL_SET_GDB_REGISTERS, CYGARC_BUS_ADDRESS, CYGARC_CACHED_ADDRESS,
196
        and CYGARC_UNCACHED_ADDRESS.
197
        * src/vectors.S: Moved exception/interrupt entry code to bank
198
        variant include file.
199
        * include/hal_var_sp.inc: Added. Contains (new) vectors.S stuff
200
        for SH2.
201
        * include/hal_var_sp.h: Added. Contains (new) hal_arch.h stuff for
202
        SH2 variant.
203
        * include/hal_var_bank.inc: Added. Contains old vectors.S stuff
204
        for SH3/SH4 variants.
205
        * include/hal_var_bank.h: Added. Contains old hal_arch.h stuff for
206
        SH3/SH4 variants.
207
 
208
        * src/hal_mk_defs.c: Added conversion for entry stack.
209
 
210
2001-11-16  Nick Garnett  
211
 
212
        * src/hal_misc.c (hal_msbit_index): Fixed this function so that it
213
        actually works!
214
 
215
2001-10-15  David Howells  
216
 
217
        * cdl/hal_sh.cdl: improved the description on the RTC constants
218
        component.
219
 
220
2001-10-11  Jesper Skov  
221
 
222
        * src/hal_mk_defs.c (main): Fixed warning.
223
 
224
2001-10-01  Jonathan Larmour  
225
 
226
        * src/sh.ld: Make separate section for GOT and .eh_frame.
227
        Make macro section for all reloc sections.
228
        Input extras.o unconditionally.
229
        * cdl/hal_sh.cdl: Don't bother with -DEXTRAS=1 - unconditional now.
230
 
231
2001-09-12  Jesper Skov  
232
 
233
        * src/vectors.S: Don't include C intr header.
234
 
235

236
 
237
        * cdl/hal_sh.cdl (CYGHWR_HAL_SH_BIGENDIAN): Set the default
238
        from what the platform requests, using the new
239
        CYGINT_HAL_SH_PLF_LITTLEENDIAN_DEFAULT CDL interface.
240
 
241
        * src/sh.ld: Support .rel.got input sections.
242
 
243
2001-09-05  Jesper Skov  
244
 
245
        * src/sh_stub.c (__single_step): Changed type 2 handling.
246
 
247
2001-08-22  Gary Thomas  
248
 
249
        * src/redboot_linux_exec.c:
250
        printf() is no longer a part of RedBoot.  Thus all programs
251
        must use diag_printf() and related functions instead.
252
 
253
2001-07-09  Jesper Skov  
254
 
255
        * src/sh_stub.c: Fixed potential SH4 problem in UBC handling.

260
        CYGARC_BUS_ADDRESS.
261
 
262
2001-06-27  Jesper Skov  
263
 
264
        * include/hal_arch.h: Added CPU address space translation macros.
265
 
266
2001-06-19  Jesper Skov  
267
 
268
        * src/redboot_linux_exec.c: Only base address, entry and cmdline
269
        options are always used. Other commands only affect image if
270
        set. This allows combined kernel&initrd images to be loaded in one
271
        file where the initrd address & size is already recorded at the
272
        start of the image.
273
 
274
        From YAEGASHI Takeshi  with a few changes:
275
        * cdl/hal_sh.cdl: Added RedBoot exec command options.
276
        * src/redboot_linux_exec.c: Added.

285
 
286
2001-01-26  Jesper Skov  
287
 
288
        * tests/intr0.c: Moved test header inclusion to proper location.
289
 
290
2001-01-18  Jesper Skov  
291
 
292
        Case 105302
293
        * src/vectors.S: Moved ILVL table to variant code.
294
        * tests/intr0.c: Added.
295
 
296
2001-01-04  Jesper Skov  
297
 
298
        * src/sh.ld: Make sure .data and .bss section sizes are aligned.
299
 
300
2000-12-13  Jesper Skov  
301
2000-12-13  Jonathan Larmour  
302

304
        startup type.
305
 
306
2000-12-08  Jesper Skov  
307
 
308
        * src/vectors.S (cyg_scheduler_sched_lock): Changed to use
309
        SYM_PTR_REF. Brian Danilko spotted this.
310
 
311
2000-11-24  Jonathan Larmour  
312
 
313
        * src/sh.ld: _reset should be adorned with CYG_LABEL_DEFN
314
        * src/vectors.S: CYG_LABEL_DEFN should have been used everywhere
315
        that CYG_LABEL_NAME was used, except for the scheduler lock which
316
        is special as it is defined in C as an asm alias.
317
        * include/arch.inc: Similarly here for symbol macros
318
 
319
        * include/basetype.h (CYG_LABEL_NAME): Delete. This is now obsolete.
320
 
321
2000-11-22  Jesper Skov  
322
 
323
        * src/sh.ld: Added mangling to all symbols.
324
        * src/vectors.S: Same. Plus introduce macro to simplify (a bit)
325
        the definition of inline immediate constants.
326

        * include/sh_regs.h: Include HAL config.
328
 
329
        * include/hal_arch.h: Don't prefix with _ in HAL_BREAKPOINT.
330
        * src/sh_stub.c: Matching changes - hack to handle both
331
        conventions.
332
 
333
        * include/basetype.h: Made CYG_LABEL_DEFN depend on toolchain.
334
 
335
        * include/arch.inc: Added symbol ref/def macros.
336
        * src/context.S: Removed FUNC_START macro.
337
 
338
2000-11-09  Jesper Skov

        * src/hal_mk_defs.c: Same.
360
 
361
        * src/vectors.S: Changed to support SH4. Moved CPU post-reset init
362
        code to variant HALs. Moved interrupt decoding to variant HAL
363
        macros. Moved cache code to variant HALs.
364

369
2000-10-23  Jesper Skov  
370
 
371
        * src/hal_misc.c: Always include hal_intr.h
372

663
        0xa0000000-0xc0000000 which is also non-cachable. The reason is

704
        * include/sh_regs.h: Replaced hardcoded baud rate constants with
705
        a macro which calculates the proper values based on baud rate
706
        and CPU clock speed.
