2
3        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
4        directly.  Supports special variants for Book E and e300 cores.  For
5        standard decrementer CPUs the new decrementer value is calculated with
6        reference to a time base so that a time drift is avoided.
7
82008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
9
10        * shared/uboot_getenv.c: New file.
11
122008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
13
14        * shared/startup/panic.c: Convention calls for leading underscore on
15        private RTEMS variables.
16
172008-05-23      Till Straumann <strauman@slac.stanford.edu>
18
19        * shared/startup/pretaskinghook.c: removed declaration
20        of BSP_vme_config() (which is already declared in
21        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
22        gcc doesn't seem to understand that the linker may
23        define this to be NULL... Silences a compiler warning
24        (and users can always provide an empty routine).
25
262008-05-22      Till Straumann <strauman@slac.stanford.edu>
27
28        * shared/startup/linkcmds, shared/startup/zerobss.c:
29        introduced '__bss_end'; assuming that __rtems_end
30        coincides with the end of .bss for the purpose of
31        zeroing .bss is very dangerous.
32
332008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
34
35        * shared/console/console.c: Fix typo.
36
372008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
38
39        * shared/console/console.c: Remove explicit switch and call
40        termios_baud_to_number().
41
422008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
43
44        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
45        Initialization Framework to ask the BSP where it has memory for the
46        RTEMS Workspace and C Program Heap. These collectively are referred
47        to as work area. If the BSP supports this, then it does not have to
48        include code to split the available memory between the two areas.
49        This reduces the amount of code in the BSP specific bspstart.c file.
50        Additionally, the shared framework can initialize the C Library, call
51        rtems_debug_enable(), and dirty the work area memory. Until most/all
52        BSPs support this new capability, if the BSP supports this, it should
53        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
54        When the transition is complete, this autoconf macro can be removed.
55
562008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
57
58        * shared/startup/bspstart.c: Refactored and renamed initialization
59        routines to rtems_initialize_data_structures,
60        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
61        rtems_initialize_start_multitasking. This opened the sequence up so
62        that bootcard() could provide a more robust and flexible framework
63        which is easier to explain and understand. This also lays the
64        groundwork for sharing the division of available memory between the
65        RTEMS workspace and heap and the C library initialization across all
66        BSPs.
67
682008-03-21      Till Straumann <strauman@slac.stanford.edu>
69
70        * shared/console/uart.c: In IRQ driven mode also
71        keep reading chars while they are available (fifo
72        could be enabled).
73
742008-03-19      Till Straumann <strauman@slac.stanford.edu>
75
76        * shared/console/console.c, shared/console/uart.c,
77        shared/console/uart.h: added support for task-driven
78        console.
79
802008-03-19      Till Straumann <strauman@slac.stanford.edu>
81
82        * shared/startup/pretaskinghook.c: install pointer
83        to rtems_malloc_sbrk_helpers_table. This (and derived)
84        BSPs rely on sbrk delivering even the first/initial
85        chunk of memory.
86
872008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
88
89        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
90        programs compiled with gcc 4.3.x can link.
91
922008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
93
94        * gen405: Remove (Abandoned).
95        * helas403: Remove (Abandoned).
96        * acinclude: Regenerate.
97
982007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
99
100        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
101        mvme3100.
102
1032007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
104
105        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
106        copies of the Configuration Table. Use the RTEMS provided accessor
107        macros to obtain configuration fields.
108
1092007-12-10      Till Straumann <strauman@slac.stanford.edu>
110
111        * Makefile.am, start/preload.S: moved preload.S
112        to ../shared/start.
113
1142007-12-10      Till Straumann <strauman@slac.stanford.edu>
115
116        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
117        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
118        to be closer to 'official' nomenclature.
119
1202007-12-10      Till Straumann <strauman@slac.stanford.edu>
121
122        * shared/openpic/openpic.c: fixed wrong register
123        address in openpic_gettimer().
124
1252007-12-10      Till Straumann <strauman@slac.stanford.edu>
126
127        * shared/motorola/vpd.c, shared/motorola/vpd.h:
128        added code (originally developed for 'beatnik')
129        to read MotLoad VPD data from i2c eeprom.
130
1312007-12-10      Till Straumann <strauman@slac.stanford.edu>
132
133        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
134        added READMEs stating that certain files should not be
135        copy/paste/modified when creating new BSPs. New BSPs
136        are encouraged to use the new library under
137        libcpu/powerpc/new-exceptions/bspsupport.
138
1392007-12-10      Till Straumann <strauman@slac.stanford.edu>
140       
141        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
142        shared/start/vectors_entry.S: moved vectors_entry.S to
143        'start' subdir and made a start file rather than
144        element of vectors.rel (it should always be linked but
145        won't if it is the sole member of vectors.rel).
146
1472007-12-08      Till Straumann <strauman@slac.stanford.edu>
148
149        * shared/vme/vme_universe.c: fixed wrong initialization
150        routine when using Tsi148 driver.
151
1522007-12-08      Till Straumann <strauman@slac.stanford.edu>
153
154        * Makefile.am: merged shared/vme/vme_universe.c and
155        shared/vme/vme_universe_dma.c into one file.
156        Added support for Tsi148 driver (DMA).
157
1582007-12-08      Till Straumann <strauman@slac.stanford.edu>
159
160        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
161        added support for Tsi148 bridge; BSP can define which
162        bridge driver to use from VMEConfig.h.
163        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
164        macro so that an error status can be passed back.
165
1662007-12-08      Till Straumann <strauman@slac.stanford.edu>
167
168        * irq_supp.h: was moved from shared/irq to
169        libcpu/powerpc/new-exceptions/bspsupport.
170
1712007-12-08      Till Straumann <strauman@slac.stanford.edu>
172
173        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
174        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
175        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
176        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
177        let C_dispatch_irq_handler() return zero to indicate to
178        low-level exception handling code that the exception
179        was handled (not used yet).
180
1812007-12-08      Till Straumann <strauman@slac.stanford.edu>
182
183        *shared/irq/irq_supp.h: removed cpp test for
184        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
185        *must* implement shared handlers.
186
1872007-12-06      Till Straumann <strauman@slac.stanford.edu>
188
189        * shared/openpic/openpic.c, shared/openpic/openpic.h:
190        added routines to set timer period and interupt mask
191        and to read current count.
192
1932007-12-06      Till Straumann <strauman@slac.stanford.edu>
194
195        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
196
1972007-12-06      Till Straumann <strauman@slac.stanford.edu>
198
199        * shared/vectors/vectors_init.c: replaced
200        switch ( current_ppc_cpu ) { } check by feature check.
201
2022007-12-06      Till Straumann <strauman@slac.stanford.edu>
203
204        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
205        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
206        run-time method to determine these bits (use settings
207        effective before exception occurred).
208        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
209        'bsp_raw_vector_is_405_critical' variable.
210
2112007-12-05      Till Straumann <strauman@slac.stanford.edu>
212
213        * shared/irq/irq_supp.h: removed stray '*/'. Removed
214        inclusion of <stdlib.h> which is unnecessary and broke
215        if_dc in an obscure way (due to malloc/free redefinition
216        in the networking code).
217
2182007-12-05      Till Straumann <strauman@slac.stanford.edu>
219
220        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
221        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
222        Converted exception vector names to new ones
223        (qualified by <cpu_type> if non-std ppc exceptions).
224
225
2262007-12-04      Till Straumann <strauman@slac.stanford.edu>
227
228        * shared/startup/bspstart.c: export BSP_commandline_string
229        variable.
230
2312007-12-04      Till Straumann <strauman@slac.stanford.edu>
232
233        * shared/flash/flash.c: added lazy init of driver
234        from BSP_flashWriteFile().
235
2362007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
237
238        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
239        Table to Configuration Table. Eliminate CPU Table from all ports.
240        Delete references to CPU Table in all forms.
241
2422007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
243
244        * shared/irq/irq.c: Spacing.
245
2462007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
247
248        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
249        fields to the Configuration Table. This included pretasking_hook,
250        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
251        extra_mpci_receive_server_stack, stack_allocate_hook, and
252        stack_free_hook. As a side-effect of this effort some multiprocessing
253        code was made conditional and some style clean up occurred.
254
2552007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
256
257        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
258        includes.
259
2602007-12-02      Till Straumann <strauman@slac.stanford.edu>
261
262        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
263        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
264        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
265        0/1 if irq was disabled/enabled prior to disabling.
266        irq_supp.h now exports a inline helper routine for scanning
267        a list of shared handlers; to be used by PIC drivers.
268
2692007-12-02      Till Straumann <strauman@slac.stanford.edu>
270
271        * shared/openpic/openpic.c shared/openpic/openpic.h,
272        shared/irq/irq_init.c: added more parameters to
273        openpic_init() so that more details of the configuration
274        can be overridden/set from the BSP. Moved setup of
275        the EPIC-specific EOI delay from BSP code into openpic_init()
276        using the new 'epic_freq' parameter.
277
2782007-12-02      Till Straumann <strauman@slac.stanford.edu>
279        * shared/openpic/openpic.c, shared/openpic/openpic.h:
280        - eliminated conditional compilation (#ifdef mpc8240)
281          The difference in register-layout between the EPIC
282          and the std. openPIC is handled by an offset parameter
283          which can be set at run-time (initialization) with
284          a new routine 'openpic_set_src_offset()'.
285        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
286          which builds the driver for big-endian register access
287          (mpc8540).
288        - openpic_disable_irq() now returns the old state so
289          that it can be restored later.
290
2912007-12-01      Till Straumann <strauman@slac.stanford.edu>
292
293        * shared/irq/openpic_i8259_irq.c:
294        - conditionally define 'irq_mask_or_tbl' only if
295          BSP_PCI_ISA_BRIDGE_IRQ is defined.
296        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
297          interrupts rather than messing with MSR directly;
298          these macros:
299            o implement compiler memory barrier
300                o will handle multiple levels (e500 'critical' interrupts)
301                  if they are ever supported.
302        - decrementer irqs are also shareable - added list traversal.
303
3042007-12-01      Till Straumann <strauman@slac.stanford.edu>
305
306        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
307        is set. The shared irq manager supports shared interrupts
308        (but requires also that the PIC-driver supports them by
309        traversing the list of shared handlers).
310        Declare C_dispatch_irq_handler() which must be defined
311        (like the other routines declared in this header) by the
312        PIC-driver.
313
3142007-12-01      Till Straumann <strauman@slac.stanford.edu>
315
316        * shared/clock/p_clock.c: (run-time) check for e500-cpu
317        and install different ISR for that type of CPU.
318
3192007-12-01      Till Straumann <strauman@slac.stanford.edu>
320
321        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
322        rather than ifdef mpc824x so that we don't depend on
323        compile-time CPU flavor. Eventually, this should become
324        a run-time check.
325
3262007-12-01      Till Straumann <strauman@slac.stanford.edu>
327
328        * shared/vectors/vectors.h: Give the BSP_Exception_frame
329        struct a name.
330
3312007-12-01      Till Straumann <strauman@slac.stanford.edu>
332
333        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
334        if the BSP-specific configuration header (VMEConfig.h)
335        defines BSP_VME_BAT_IDX so that this file can be used
336        on CPUs w/o bats (e500).
337
3382007-11-30      Till Straumann <strauman@slac.stanford.edu>
339
340        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
341
3422007-11-30      Till Straumann <strauman@slac.stanford.edu>
343
344        * shared/startup/pretaskinghook.c: Replaced inclusion of
345        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
346        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
347
3482007-11-30      Till Straumann <strauman@slac.stanford.edu>
349
350        * shared/startup/bspstart.c: Removed excess /*, replaced
351        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
352        there should be run-time checks.
353
3542007-11-30      Till Straumann <strauman@slac.stanford.edu>
355
356        * shared/motorola/motorola.c: removed excess initializer
357        elements.
358
3592007-11-30      Till Straumann <strauman@slac.stanford.edu>
360
361        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
362        shared/irq/irq_supp.h (added):
363        Removed 'is_processor_irq()' from irq.c; the BSP routines
364        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
365        to ignore processor irqs anyways. Removed
366        all BSP-defined constants from irq.c. This makes irq.c (almost)
367        binary-compatible among BSPs (ultimate goal is making 'shared'
368        a library).
369        Added a header (irq_supp.h) defining the interface between
370        the generic interrupt manager (irq.c) and the routines it
371        requires to be supplied by the BSP (eventually, these
372        should go into rtems/irq.h).
373
3742007-11-30      Till Straumann <strauman@slac.stanford.edu>
375
376        * shared/irq/irq.h, shared/irq/irq_init.c: Removed the definition
377        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
378        initialize the irqBase member of the rtems_irq_global_settings
379        struct. However, irqBase is an rtems_irq_symbolic_name,
380        so using BSP_LOWEST_OFFSET is more appropriate.
381
3822007-11-28      Joel Sherrill <joel.sherrill@OARcorp.com>
383
384        * shared/startup/bspstart.c: Eliminate PowerPC specific elements from
385        the CPU Table. They have been replaced with variables named bsp_XXX
386        as needed.
387
3882007-11-29      Till Straumann <strauman@slac.stanford.edu>
389
390        * Makefile.am, shared/flash, shared/flash/flash.c,
391        shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h,
392        shared/flash/intelFlash.c, shared/flash/spansionFlash.c:
393        Added flash programmer API, implementation and chip drivers
394        for some intel + spansion flash chips (as found on mvme5500,
395        mvme6100 and mvme3100 boards).
396        A more appopriate place would probably be libchip but
397        I don't know if the API is acceptable and if the implementation
398        is generic enough (e.g., no CFI support) so I leave it here
399        for now.

406
407        * shared/console/uart.c: when draining UART during
408        initialization (wait for possible printk() activity
409        to finish) look at TEMT (fifo, holding-reg and shift-reg)
410        rather than THRE (fifo, holding-reg only). This resolved
411        some scrambled output issues for me.
412
413        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
414        value then the driver interprets the modulus as a speed value
415        and uses the current setting of the divisor to compute the
416        clock speed (BSPBaseBaud). This is useful if you have a board
417        that you know is initialized e.g., to 9600 but you
418        don't know the clock speed.

1211        This modification is part of the submitted modifications necessary
1212        to
1213        support the IBM PPC405 family.  This submission was reviewed by
1214        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1215        not negatively impact the ppc403 BSPs.  The submission and tracking
1216        process was captured as PR50.
1217        * ChangeLog: Removed bogus comment on edit of generated file.
1218        * acinclude.m4: Added gen405 BSP.

1251
1252        * shared/start/start.S: Increased BAT0 mapping of RAM from 64 meg to
1253        256 meg to allow operation on boards with larger RAM sizes.
1254        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1255        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1256        function to allow operation on boards with CPUs other than the
1257        MPC750.

1269        shared/startup/bspstart.c, shared/vectors/vectors.S,
1270        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1271        "libbsp/powerpc/shared" BSP has been modified considerably with the
1272        goal to make it more flexible and reusable by other BSPs. The main
1273        strategies were: - eliminate hardcoded base addresses; devices use
1274        offsets and a BSP defined base address. - separate functionality
1275        into different files (e.g. reboot from inch.c to reboot.c) which can
1276        be overridden by a 'derived' BSP. - separate initialization code
1277        into separate files (e.g.  PCI bridge detection/initialization was
1278        separated from the more generic PCI access routines), also to make
1279        it easier for 'derived' BSPs to substitute their own initialization
1280        code. There are also a couple of enhancements and fixes: - IRQ
1281        handling code now has a hook for attaching a VME bridge. - OpenPIC
1282        is now explicitely initialized (polarities, senses). Eliminated the
1283        implicit assumption on the presence of an ISA PIC. - UART and
1284        console driver now supports more than 1 port. The current maximum of
1285        2 can easily be extended by enlarging a table (it would even be
1286        easier if the ISR API was not broken by design). - fixed polled_io.c
1287        so it correctly supports console on COM2 - fixed TLB invalidation
1288        code (start.S). - exception handler prints a stack backtrace. -
1289        added BSP_pciFindDevice() to scan the pci bus for a particular
1290        vendor/device/instance.

1293
1294        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1295        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1296        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1297        direction of segments to memory regions may also have been
1298        addressed.  This was a sweep across all BSPs.
1299
13002001-04-08      Joel Sherrill <joel@OARcorp.com>
1301
1302        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame
1303
13042001-03-30      Eric Valette <valette@crf.canon.fr>
1305
1306        * shared/Makefile.am, shared/console/consoleIo.h,
1307        shared/include/bsp.h: These modifications are part of the conversion
1308        of the mpc8xx CPU to the "new exception processing model."
1309        * configure.in, motorola_powerpc/Makefile.am,
1310        motorola_powerpc/configure.in: These modifications are in support of
1311        switching the mpc8xx to the use the "new exception processing
1312        model."
1313
13142000-11-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1315
1316        * Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
1317
13182000-11-02      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1319
1320        * Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
1321        $(RTEMS_TOPdir)/aclocal.
1322
13232000-11-01      Joel Sherrill <joel@OARcorp.com>
1324
1325        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1326        and libcsupport.h moved from libc to lib/include/rtems and now must
1327        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1328        while doing this.
1329
13302000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>
1331
1332        * Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
1333        GNU canonicalization.
1334
13352000-09-29      Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
1336
1337        * shared/startup/linkcmds: Added lines so DWARF debug information
1338        would be available.  Otherwise gdb complains that the offsets for
1339        the debug info are incorrect and doesn't load the files.
1340
13412000-09-05      Joel Sherrill <joel@OARcorp.com>
1342
1343        * shared/start/start.S: Include proper files to compile.
