  • shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP Initialization Framework to ask the BSP where it has memory for the RTEMS Workspace and C Program Heap. These collectively are referred to as work area. If the BSP supports this, then it does not have to include code to split the available memory between the two areas. This reduces the amount of code in the BSP specific bspstart.c file. Additionally, the shared framework can initialize the C Library, call rtems_debug_enable(), and dirty the work area memory. Until most/all BSPs support this new capability, if the BSP supports this, it should call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac. When the transition is complete, this autoconf macro can be removed.
  • Property mode set to 100644

3        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
4        Initialization Framework to ask the BSP where it has memory for the
5        RTEMS Workspace and C Program Heap. These collectively are referred
6        to as work area. If the BSP supports this, then it does not have to
7        include code to split the available memory between the two areas.
8        This reduces the amount of code in the BSP specific bspstart.c file.
9        Additionally, the shared framework can initialize the C Library, call
10        rtems_debug_enable(), and dirty the work area memory. Until most/all
11        BSPs support this new capability, if the BSP supports this, it should
12        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
13        When the transition is complete, this autoconf macro can be removed.

152008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
16
17        * shared/startup/bspstart.c: Refactored and renamed initialization
18        routines to rtems_initialize_data_structures,
19        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
20        rtems_initialize_start_multitasking. This opened the sequence up so
21        that bootcard() could provide a more robust and flexible framework
22        which is easier to explain and understand. This also lays the
23        groundwork for sharing the division of available memory between the
24        RTEMS workspace and heap and the C library initialization across all
25        BSPs.
26
272008-03-21      Till Straumann <strauman@slac.stanford.edu>
28
29        * shared/console/uart.c: In IRQ driven mode also
30        keep reading chars while they are available (fifo
31        could be enabled).
32
332008-03-19      Till Straumann <strauman@slac.stanford.edu>
34
35        * shared/console/console.c, shared/console/uart.c,
36        shared/console/uart.h: added support for task-driven
37        console.
38
392008-03-19      Till Straumann <strauman@slac.stanford.edu>
40
41        * shared/startup/pretaskinghook.c: install pointer
42        to rtems_malloc_sbrk_helpers_table. This (and derived)
43        BSPs rely on sbrk delivering even the first/initial
44        chunk of memory.
45
462008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
47
48        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
49        programs compiled with gcc 4.3.x can link.
50
512008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
52
53        * gen405: Remove (Abandoned).
54        * helas403: Remove (Abandoned).
55        * acinclude: Regenerate.
56
572007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
58
59        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
60        mvme3100.
61
622007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
63
64        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
65        copies of the Configuration Table. Use the RTEMS provided accessor
66        macros to obtain configuration fields.
67
682007-12-10      Till Straumann <strauman@slac.stanford.edu>
69
70        * Makefile.am, start/preload.S: moved preload.S
71        to ../shared/start.
72
732007-12-10      Till Straumann <strauman@slac.stanford.edu>
74
75        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
76        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
77        to be closer to 'official' nomenclature.
78
792007-12-10      Till Straumann <strauman@slac.stanford.edu>
80
81        * shared/openpic/openpic.c: fixed wrong register
82        address in openpic_gettimer().
83
842007-12-10      Till Straumann <strauman@slac.stanford.edu>
85
86        * shared/motorola/vpd.c, shared/motorola/vpd.h:
87        added code (originally developed for 'beatnik')
88        to read MotLoad VPD data from i2c eeprom.
89
902007-12-10      Till Straumann <strauman@slac.stanford.edu>
91
92        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
93        added READMEs stating that certain files should not be
94        copy/paste/modified when creating new BSPs. New BSPs
95        are encouraged to use the new library under
96        libcpu/powerpc/new-exceptions/bspsupport.
97
982007-12-10      Till Straumann <strauman@slac.stanford.edu>
99       
100        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
101        shared/start/vectors_entry.S: moved vectors_entry.S to
102        'start' subdir and made a start file rather than
103        element of vectors.rel (it should always be linked but
104        won't if it is the sole member of vectors.rel).
105
1062007-12-08      Till Straumann <strauman@slac.stanford.edu>
107
108        * shared/vme/vme_universe.c: fixed wrong initialization
109        routine when using Tsi148 driver.
110
1112007-12-08      Till Straumann <strauman@slac.stanford.edu>
112
113        * Makefile.am: merged shared/vme/vme_universe.c and
114        shared/vme/vme_universe_dma.c into one file.
115        Added support for Tsi148 driver (DMA).
116
1172007-12-08      Till Straumann <strauman@slac.stanford.edu>
118
119        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
120        added support for Tsi148 bridge; BSP can define which
121        bridge driver to use from VMEConfig.h.
122        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
123        macro so that an error status can be passed back.
124
1252007-12-08      Till Straumann <strauman@slac.stanford.edu>
126
127        * irq_supp.h: was moved from shared/irq to
128        libcpu/powerpc/new-exceptions/bspsupport.
129
1302007-12-08      Till Straumann <strauman@slac.stanford.edu>
131
132        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
133        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
134        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
135        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
136        let C_dispatch_irq_handler() return zero to indicate to
137        low-level exception handling code that the exception
138        was handled (not used yet).
139
1402007-12-08      Till Straumann <strauman@slac.stanford.edu>
141
142        *shared/irq/irq_supp.h: removed cpp test for
143        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
144        *must* implement shared handlers.
145
1462007-12-06      Till Straumann <strauman@slac.stanford.edu>
147
148        * shared/openpic/openpic.c, shared/openpic/openpic.h:
149        added routines to set timer period and interupt mask
150        and to read current count.
151
1522007-12-06      Till Straumann <strauman@slac.stanford.edu>
153
154        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
155
1562007-12-06      Till Straumann <strauman@slac.stanford.edu>
157
158        * shared/vectors/vectors_init.c: replaced
159        switch ( current_ppc_cpu ) { } check by feature check.
160
1612007-12-06      Till Straumann <strauman@slac.stanford.edu>
162
163        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
164        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
165        run-time method to determine these bits (use settings
166        effective before exception occurred).
167        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
168        'bsp_raw_vector_is_405_critical' variable.
169
1702007-12-05      Till Straumann <strauman@slac.stanford.edu>
171
172        * shared/irq/irq_supp.h: removed stray '*/'. Removed
173        inclusion of <stdlib.h> which is unnecessary and broke
174        if_dc in an obscure way (due to malloc/free redefinition
175        in the networking code).
176
1772007-12-05      Till Straumann <strauman@slac.stanford.edu>
178
179        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
180        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
181        Converted exception vector names to new ones
182        (qualified by <cpu_type> if non-std ppc exceptions).
183
184
1852007-12-04      Till Straumann <strauman@slac.stanford.edu>
186
187        * shared/startup/bspstart.c: export BSP_commandline_string
188        variable.
189
1902007-12-04      Till Straumann <strauman@slac.stanford.edu>
191
192        * shared/flash/flash.c: added lazy init of driver
193        from BSP_flashWriteFile().
194
1952007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
196
197        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
198        Table to Configuration Table. Eliminate CPU Table from all ports.
199        Delete references to CPU Table in all forms.
200
2012007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
202
203        * shared/irq/irq.c: Spacing.
204
2052007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
206
207        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
208        fields to the Configuration Table. This included pretasking_hook,
209        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
210        extra_mpci_receive_server_stack, stack_allocate_hook, and
211        stack_free_hook. As a side-effect of this effort some multiprocessing
212        code was made conditional and some style clean up occurred.
213
2142007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
215
216        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
217        includes.
218
2192007-12-02      Till Straumann <strauman@slac.stanford.edu>
220
221        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
222        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
223        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
224        0/1 if irq was disabled/enabled prior to disabling.
225        irq_supp.h now exports a inline helper routine for scanning
226        a list of shared handlers; to be used by PIC drivers.
227
2282007-12-02      Till Straumann <strauman@slac.stanford.edu>
229
230        * shared/openpic/openpic.c shared/openpic/openpic.h,
231        shared/irq/irq_init.c: added more parameters to
232        openpic_init() so that more details of the configuration
233        can be overridden/set from the BSP. Moved setup of
234        the EPIC-specific EOI delay from BSP code into openpic_init()
235        using the new 'epic_freq' parameter.
236
2372007-12-02      Till Straumann <strauman@slac.stanford.edu>
238        * shared/openpic/openpic.c, shared/openpic/openpic.h:
239        - eliminated conditional compilation (#ifdef mpc8240)
240          The difference in register-layout between the EPIC
241          and the std. openPIC is handled by an offset parameter
242          which can be set at run-time (initialization) with
243          a new routine 'openpic_set_src_offset()'.
244        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
245          which builds the driver for big-endian register access
246          (mpc8540).
247        - openpic_disable_irq() now returns the old state so
248          that it can be restored later.
249
2502007-12-01      Till Straumann <strauman@slac.stanford.edu>
251
252        * shared/irq/openpic_i8259_irq.c:
253        - conditionally define 'irq_mask_or_tbl' only if
254          BSP_PCI_ISA_BRIDGE_IRQ is defined.
255        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
256          interrupts rather than messing with MSR directly;
257          these macros:
258            o implement compiler memory barrier
259                o will handle multiple levels (e500 'critical' interrupts)
260                  if they are ever supported.
261        - decrementer irqs are also shareable - added list traversal.
262
2632007-12-01      Till Straumann <strauman@slac.stanford.edu>
264
265        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
266        is set. The shared irq manager supports shared interrupts
267        (but requires also that the PIC-driver supports them by
268        traversing the list of shared handlers).
269        Declare C_dispatch_irq_handler() which must be defined
270        (like the other routines declared in this header) by the
271        PIC-driver.
272
2732007-12-01      Till Straumann <strauman@slac.stanford.edu>
274
275        * shared/clock/p_clock.c: (run-time) check for e500-cpu
276        and install different ISR for that type of CPU.
277
2782007-12-01      Till Straumann <strauman@slac.stanford.edu>
279
280        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
281        rather than ifdef mpc824x so that we don't depend on
282        compile-time CPU flavor. Eventually, this should become
283        a run-time check.
284
2852007-12-01      Till Straumann <strauman@slac.stanford.edu>
286
287        * shared/vectors/vectors.h: Give the BSP_Exception_frame
288        struct a name.
289
2902007-12-01      Till Straumann <strauman@slac.stanford.edu>
291
292        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
293        if the BSP-specific configuration header (VMEConfig.h)
294        defines BSP_VME_BAT_IDX so that this file can be used
295        on CPUs w/o bats (e500).
296
2972007-11-30      Till Straumann <strauman@slac.stanford.edu>
298
299        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
300
3012007-11-30      Till Straumann <strauman@slac.stanford.edu>
302
303        * shared/startup/pretaskinghook.c: Replaced inclusion of
304        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
305        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
306
3072007-11-30      Till Straumann <strauman@slac.stanford.edu>
308
309        * shared/startup/bspstart.c: Removed excess /*, replaced
310        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
311        there should be run-time checks.
312
3132007-11-30      Till Straumann <strauman@slac.stanford.edu>
314
315        * shared/motorola/motorola.c: removed excess initializer
316        elements.
317
3182007-11-30      Till Straumann <strauman@slac.stanford.edu>
319
320        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
321        shared/irq/irq_supp.h (added):
322        Removed 'is_processor_irq()' from irq.c; the BSP routines
323        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
324        to ignore processor irqs anyways. Removed
325        all BSP-defined constants from irq.c. This makes irq.c (almost)
326        binary-compatible among BSPs (ultimate goal is making 'shared'
327        a library).
328        Added a header (irq_supp.h) defining the interface between
329        the generic interrupt manager (irq.c) and the routines it
330        requires to be supplied by the BSP (eventually, these
331        should go into rtems/irq.h).
332
3332007-11-30      Till Straumann <strauman@slac.stanford.edu>
334
335        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition
336        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
337        initialize the irqBase member of the rtems_irq_global_settings
338        struct. However, irqBase is an rtems_irq_symbolic_name,
339        so using BSP_LOWEST_OFFSET is more appropriate.
340
3412007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
342
343        * shared/startup/bspstart.c: Eliminate PowerPC specific elements from
344        the CPU Table. They have been replaced with variables named bsp_XXX
345        as needed.
346
3472007-11-29      Till Straumann <strauman@slac.stanford.edu>
348
349        * Makefile.am, shared/flash, shared/flash/flash.c,
350        shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h,
351        shared/flash/intelFlash.c, shared/flash/spansionFlash.c:
352        Added flash programmer API, implementation and chip drivers
353        for some intel + spansion flash chips (as found on mvme5500,
354        mvme6100 and mvme3100 boards).
355        A more appopriate place would probably be libchip but
356        I don't know if the API is acceptable and if the implementation
357        is generic enough (e.g., no CFI support) so I leave it here
358        for now.
359
3602007-11-26      Joel Sherrill <joel.sherrill@OARcorp.com>
361
362        * shared/console/uart.c: Fix typo and spacing.
363
3642007-11-21      Till Straumann <strauman@slac.stanford.edu>
365
366        * shared/console/uart.c: when draining UART during
367        initialization (wait for possible printk() activity
368        to finish) look at TEMT (fifo, holding-reg and shift-reg)
369        rather than THRE (fifo, holding-reg only). This resolved
370        some scrambled output issues for me.
371
372        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
373        value then the driver interprets the modulus as a speed value
374        and uses the current setting of the divisor to compute the
375        clock speed (BSPBaseBaud). This is useful if you have a board
376        that you know is initialized e.g., to 9600 but you
377        don't know the clock speed.
378
3792007-11-21      Till Straumann <strauman@slac.stanford.edu>
380
381        * Makefile.am, motorola_powerpc/Makefile.am,
382        * shared/pci/detect_raven_bridge.c, Makefile.am,
383        * shared/pci/generic_clear_hberrs.c: separated the generic
384        version of _BSP_clear_hostbridge_errors() into its own
385        file.
386
3872007-11-06      Till Straumann <strauman@slac.stanford.edu>

1170        This modification is part of the submitted modifications necessary
1171        to
1172        support the IBM PPC405 family.  This submission was reviewed by
1173        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1174        not negatively impact the ppc403 BSPs.  The submission and tracking
1175        process was captured as PR50.
1176        * ChangeLog: Removed bogus comment on edit of generated file.
1177        * acinclude.m4: Added gen405 BSP.

1211        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
1212        256 meg to allow operation on boards with larger RAM sizes.
1213        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1214        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1215        function to allow operation on boards with CPUs other than the
1216        MPC750.

1229        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1230        "libbsp/powerpc/shared" BSP has been modified considerably with the
1231        goal to make it more flexible and reusable by other BSPs. The main
1232        strategies were: - eliminate hardcoded base addresses; devices use
1233        offsets and a BSP defined base address. - separate functionality
1234        into different files (e.g. reboot from inch.c to reboot.c) which can
1235        be overridden by a 'derived' BSP. - separate initialization code
1236        into separate files (e.g.  PCI bridge detection/initialization was
1237        separated from the more generic PCI access routines), also to make
1238        it easier for 'derived' BSPs to substitute their own initialization
1239        code. There are also a couple of enhancements and fixes: - IRQ
1240        handling code now has a hook for attaching a VME bridge. - OpenPIC
1241        is now explicitely initialized (polarities, senses). Eliminated the
1242        implicit assumption on the presence of an ISA PIC. - UART and
1243        console driver now supports more than 1 port. The current maximum of
1244        2 can easily be extended by enlarging a table (it would even be
1245        easier if the ISR API was not broken by design). - fixed polled_io.c
1246        so it correctly supports console on COM2 - fixed TLB invalidation
1247        code (start.S). - exception handler prints a stack backtrace. -
1248        added BSP_pciFindDevice() to scan the pci bus for a particular
1249        vendor/device/instance.

1253        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1254        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1255        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1256        direction of segments to memory regions may also have been
1257        addressed.  This was a sweep across all BSPs.
1258
12592001-04-08      Joel Sherrill <joel@OARcorp.com>
1260
1261        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

1264
1265        * shared/Makefile.am, shared/console/consoleIo.h,
1266        shared/include/bsp.h: These modifications are part of the conversion
1267        of the mpc8xx CPU to the "new exception processing model."
1268        * configure.in, motorola_powerpc/Makefile.am,
1269        motorola_powerpc/configure.in: These modifications are in support of
1270        switching the mpc8xx to the use the "new exception processing
1271        model."

12732000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

1275        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
1276
12772000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1278
1279        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
1280        $(RTEMS_TOPdir)/aclocal.
1281
12822000-11-01      Joel Sherrill <joel@OARcorp.com>
1283
1284        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1285        and libcsupport.h moved from libc to lib/include/rtems and now must
1286        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1287        while doing this.
1288
12892000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

1291        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
1292        GNU canonicalization.

12942000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
1295
1296        * shared/startup/linkcmds: Added lines so DWARF debug information
1297        would be available.  Otherwise gdb complains that the offsets for
1298        the debug info are incorrect and doesn't load the files.
