3        * mpc55xxevb: New BSP.
4
52008-07-14      Thomas Doefler <Thomas.Doerfler@embedded-brains.de>
6        * haleakala: added new BSP
7
82008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
9
10        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
11        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
12        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
13        used to store the interrupt disable mask.  See bootcard.c and
14        ppc_exc_initialize() for default initialization.
15
16        Update to new exception initialization routine ppc_exc_initialize().
17        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
18
19        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
20        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
21        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
22        used to store the interrupt disable mask.  See bootcard.c for default
23        initialization.
24
252008-07-10      Till Straumann <strauman@slac.stanford.edu>
26
27        * shared/flash/spansionFlash.c: removed "m" memory
28        operands.
29
302008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
31
32        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
33        directly.  Supports special variants for Book E and e300 cores.  For
34        standard decrementer CPUs the new decrementer value is calculated with
35        reference to a time base so that a time drift is avoided.
36
372008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
38
39        * shared/uboot_getenv.c: New file.
40
412008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
42
43        * shared/startup/panic.c: Convention calls for leading underscore on
44        private RTEMS variables.
45
462008-05-23      Till Straumann <strauman@slac.stanford.edu>
47
48        * shared/startup/pretaskinghook.c: removed declaration
49        of BSP_vme_config() (which is already declared in
50        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
51        gcc doesn't seem to understand that the linker may
52        define this to be NULL... Silences a compiler warning
53        (and users can always provide an empty routine).
54
552008-05-22      Till Straumann <strauman@slac.stanford.edu>
56
57        * shared/startup/linkcmds, shared/startup/zerobss.c:
58        introduced '__bss_end'; assuming that __rtems_end
59        coincides with the end of .bss for the purpose of
60        zeroing .bss is very dangerous.
61
622008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
63
64        * shared/console/console.c: Fix typo.
65
662008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
67
68        * shared/console/console.c: Remove explicit switch and call
69        termios_baud_to_number().
70
712008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
72
73        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
74        Initialization Framework to ask the BSP where it has memory for the
75        RTEMS Workspace and C Program Heap. These collectively are referred
76        to as work area. If the BSP supports this, then it does not have to
77        include code to split the available memory between the two areas.
78        This reduces the amount of code in the BSP specific bspstart.c file.
79        Additionally, the shared framework can initialize the C Library, call
80        rtems_debug_enable(), and dirty the work area memory. Until most/all
81        BSPs support this new capability, if the BSP supports this, it should
82        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
83        When the transition is complete, this autoconf macro can be removed.
84
852008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
86
87        * shared/startup/bspstart.c: Refactored and renamed initialization
88        routines to rtems_initialize_data_structures,
89        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
90        rtems_initialize_start_multitasking. This opened the sequence up so
91        that bootcard() could provide a more robust and flexible framework
92        which is easier to explain and understand. This also lays the
93        groundwork for sharing the division of available memory between the
94        RTEMS workspace and heap and the C library initialization across all
95        BSPs.
96
972008-03-21      Till Straumann <strauman@slac.stanford.edu>
98
99        * shared/console/uart.c: In IRQ driven mode also
100        keep reading chars while they are available (fifo
101        could be enabled).
102
1032008-03-19      Till Straumann <strauman@slac.stanford.edu>
104
105        * shared/console/console.c, shared/console/uart.c,
106        shared/console/uart.h: added support for task-driven
107        console.
108
1092008-03-19      Till Straumann <strauman@slac.stanford.edu>
110
111        * shared/startup/pretaskinghook.c: install pointer
112        to rtems_malloc_sbrk_helpers_table. This (and derived)
113        BSPs rely on sbrk delivering even the first/initial
114        chunk of memory.
115
1162008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
117
118        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
119        programs compiled with gcc 4.3.x can link.
120
1212008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
122
123        * gen405: Remove (Abandoned).
124        * helas403: Remove (Abandoned).
125        * acinclude: Regenerate.
126
1272007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
128
129        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
130        mvme3100.
131
1322007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
133
134        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
135        copies of the Configuration Table. Use the RTEMS provided accessor
136        macros to obtain configuration fields.
137
1382007-12-10      Till Straumann <strauman@slac.stanford.edu>
139
140        * Makefile.am, start/preload.S: moved preload.S
141        to ../shared/start.
142
1432007-12-10      Till Straumann <strauman@slac.stanford.edu>
144
145        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
146        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
147        to be closer to 'official' nomenclature.
148
1492007-12-10      Till Straumann <strauman@slac.stanford.edu>
150
151        * shared/openpic/openpic.c: fixed wrong register
152        address in openpic_gettimer().
153
1542007-12-10      Till Straumann <strauman@slac.stanford.edu>
155
156        * shared/motorola/vpd.c, shared/motorola/vpd.h:
157        added code (originally developed for 'beatnik')
158        to read MotLoad VPD data from i2c eeprom.
159
1602007-12-10      Till Straumann <strauman@slac.stanford.edu>
161
162        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
163        added READMEs stating that certain files should not be
164        copy/paste/modified when creating new BSPs. New BSPs
165        are encouraged to use the new library under
166        libcpu/powerpc/new-exceptions/bspsupport.
167
1682007-12-10      Till Straumann <strauman@slac.stanford.edu>
169       
170        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
171        shared/start/vectors_entry.S: moved vectors_entry.S to
172        'start' subdir and made a start file rather than
173        element of vectors.rel (it should always be linked but
174        won't if it is the sole member of vectors.rel).
175
1762007-12-08      Till Straumann <strauman@slac.stanford.edu>
177
178        * shared/vme/vme_universe.c: fixed wrong initialization
179        routine when using Tsi148 driver.
180
1812007-12-08      Till Straumann <strauman@slac.stanford.edu>
182
183        * Makefile.am: merged shared/vme/vme_universe.c and
184        shared/vme/vme_universe_dma.c into one file.
185        Added support for Tsi148 driver (DMA).
186
1872007-12-08      Till Straumann <strauman@slac.stanford.edu>
188
189        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
190        added support for Tsi148 bridge; BSP can define which
191        bridge driver to use from VMEConfig.h.
192        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
193        macro so that an error status can be passed back.
194
1952007-12-08      Till Straumann <strauman@slac.stanford.edu>
196
197        * irq_supp.h: was moved from shared/irq to
198        libcpu/powerpc/new-exceptions/bspsupport.
199
2002007-12-08      Till Straumann <strauman@slac.stanford.edu>
201
202        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
203        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
204        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
205        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
206        let C_dispatch_irq_handler() return zero to indicate to
207        low-level exception handling code that the exception
208        was handled (not used yet).
209
2102007-12-08      Till Straumann <strauman@slac.stanford.edu>
211
212        *shared/irq/irq_supp.h: removed cpp test for
213        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
214        *must* implement shared handlers.
215
2162007-12-06      Till Straumann <strauman@slac.stanford.edu>
217
218        * shared/openpic/openpic.c, shared/openpic/openpic.h:
219        added routines to set timer period and interupt mask
220        and to read current count.
221
2222007-12-06      Till Straumann <strauman@slac.stanford.edu>
223
224        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
225
2262007-12-06      Till Straumann <strauman@slac.stanford.edu>
227
228        * shared/vectors/vectors_init.c: replaced
229        switch ( current_ppc_cpu ) { } check by feature check.
230
2312007-12-06      Till Straumann <strauman@slac.stanford.edu>
232
233        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
234        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
235        run-time method to determine these bits (use settings
236        effective before exception occurred).
237        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
238        'bsp_raw_vector_is_405_critical' variable.
239
2402007-12-05      Till Straumann <strauman@slac.stanford.edu>
241
242        * shared/irq/irq_supp.h: removed stray '*/'. Removed
243        inclusion of <stdlib.h> which is unnecessary and broke
244        if_dc in an obscure way (due to malloc/free redefinition
245        in the networking code).
246
2472007-12-05      Till Straumann <strauman@slac.stanford.edu>
248
249        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
250        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
251        Converted exception vector names to new ones
252        (qualified by <cpu_type> if non-std ppc exceptions).
253
254
2552007-12-04      Till Straumann <strauman@slac.stanford.edu>
256
257        * shared/startup/bspstart.c: export BSP_commandline_string
258        variable.
259
2602007-12-04      Till Straumann <strauman@slac.stanford.edu>
261
262        * shared/flash/flash.c: added lazy init of driver
263        from BSP_flashWriteFile().
264
2652007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
266
267        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
268        Table to Configuration Table. Eliminate CPU Table from all ports.
269        Delete references to CPU Table in all forms.
270
2712007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
272
273        * shared/irq/irq.c: Spacing.
274
2752007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
276
277        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
278        fields to the Configuration Table. This included pretasking_hook,
279        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
280        extra_mpci_receive_server_stack, stack_allocate_hook, and
281        stack_free_hook. As a side-effect of this effort some multiprocessing
282        code was made conditional and some style clean up occurred.
283
2842007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
285
286        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
287        includes.
288
2892007-12-02      Till Straumann <strauman@slac.stanford.edu>
290
291        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
292        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
293        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
294        0/1 if irq was disabled/enabled prior to disabling.
295        irq_supp.h now exports a inline helper routine for scanning
296        a list of shared handlers; to be used by PIC drivers.
297
2982007-12-02      Till Straumann <strauman@slac.stanford.edu>
299
300        * shared/openpic/openpic.c shared/openpic/openpic.h,
301        shared/irq/irq_init.c: added more parameters to
302        openpic_init() so that more details of the configuration
303        can be overridden/set from the BSP. Moved setup of
304        the EPIC-specific EOI delay from BSP code into openpic_init()
305        using the new 'epic_freq' parameter.
306
3072007-12-02      Till Straumann <strauman@slac.stanford.edu>
308        * shared/openpic/openpic.c, shared/openpic/openpic.h:
309        - eliminated conditional compilation (#ifdef mpc8240)
310          The difference in register-layout between the EPIC
311          and the std. openPIC is handled by an offset parameter
312          which can be set at run-time (initialization) with
313          a new routine 'openpic_set_src_offset()'.
314        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
315          which builds the driver for big-endian register access
316          (mpc8540).
317        - openpic_disable_irq() now returns the old state so
318          that it can be restored later.
319
3202007-12-01      Till Straumann <strauman@slac.stanford.edu>
321
322        * shared/irq/openpic_i8259_irq.c:
323        - conditionally define 'irq_mask_or_tbl' only if
324          BSP_PCI_ISA_BRIDGE_IRQ is defined.
325        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
326          interrupts rather than messing with MSR directly;
327          these macros:
328            o implement compiler memory barrier
329                o will handle multiple levels (e500 'critical' interrupts)
330                  if they are ever supported.
331        - decrementer irqs are also shareable - added list traversal.
332
3332007-12-01      Till Straumann <strauman@slac.stanford.edu>
334
335        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
336        is set. The shared irq manager supports shared interrupts
337        (but requires also that the PIC-driver supports them by
338        traversing the list of shared handlers).
339        Declare C_dispatch_irq_handler() which must be defined
340        (like the other routines declared in this header) by the
341        PIC-driver.
342
3432007-12-01      Till Straumann <strauman@slac.stanford.edu>
344
345        * shared/clock/p_clock.c: (run-time) check for e500-cpu
346        and install different ISR for that type of CPU.
347
3482007-12-01      Till Straumann <strauman@slac.stanford.edu>
349
350        * shared/pci/detect_raven_bridge.c: use ifdef mvme2100
351        rather than ifdef mpc824x so that we don't depend on
352        compile-time CPU flavor. Eventually, this should become
353        a run-time check.
354
3552007-12-01      Till Straumann <strauman@slac.stanford.edu>
356
357        * shared/vectors/vectors.h: Give the BSP_Exception_frame
358        struct a name.
359
3602007-12-01      Till Straumann <strauman@slac.stanford.edu>
361
362        * shared/vme/vmeconfig.c: Include <libcpu/bat.h> only
363        if the BSP-specific configuration header (VMEConfig.h)
364        defines BSP_VME_BAT_IDX so that this file can be used
365        on CPUs w/o bats (e500).
366
3672007-11-30      Till Straumann <strauman@slac.stanford.edu>
368
369        * shared/startup/bspstart: removed _Cpu_table.exceptions_in_RAM.
370
3712007-11-30      Till Straumann <strauman@slac.stanford.edu>
372
373        * shared/startup/pretaskinghook.c: Replaced inclusion of
374        <bsp/consoleIo.h> by <rtems/bspIo.> (for printk) and
375        made it conditional on #ifdef SHOW_MORE_INIT_SETTINGS.
376
3772007-11-30      Till Straumann <strauman@slac.stanford.edu>
378
379        * shared/startup/bspstart.c: Removed excess /*, replaced
380        #ifdef checks for mpc8240 by #ifdef mvme2100; eventually
381        there should be run-time checks.
382
3832007-11-30      Till Straumann <strauman@slac.stanford.edu>
384
385        * shared/motorola/motorola.c: removed excess initializer
386        elements.
387
3882007-11-30      Till Straumann <strauman@slac.stanford.edu>
389
390        * shared/irq/irq.h, shared/irq/irq.c, shared/irq/irq_init.c,
391        shared/irq/irq_supp.h (added):
392        Removed 'is_processor_irq()' from irq.c; the BSP routines
393        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
394        to ignore processor irqs anyways. Removed
395        all BSP-defined constants from irq.c. This makes irq.c (almost)
396        binary-compatible among BSPs (ultimate goal is making 'shared'
397        a library).
398        Added a header (irq_supp.h) defining the interface between
399        the generic interrupt manager (irq.c) and the routines it
400        requires to be supplied by the BSP (eventually, these

409        so using BSP_LOWEST_OFFSET is more appropriate.

423        for some intel + spansion flash chips (as found on mvme5500,

425        A more appopriate place would probably be libchip but
426        I don't know if the API is acceptable and if the implementation
427        is generic enough (e.g., no CFI support) so I leave it here

436        * shared/console/uart.c: when draining UART during
437        initialization (wait for possible printk() activity
438        to finish) look at TEMT (fifo, holding-reg and shift-reg)
439        rather than THRE (fifo, holding-reg only). This resolved
440        some scrambled output issues for me.
441
442        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
443        value then the driver interprets the modulus as a speed value
444        and uses the current setting of the divisor to compute the
445        clock speed (BSPBaseBaud). This is useful if you have a board
446        that you know is initialized e.g., to 9600 but you
447        don't know the clock speed.

1240        This modification is part of the submitted modifications necessary
1241        to
1242        support the IBM PPC405 family.  This submission was reviewed by
1243        Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did
1244        not negatively impact the ppc403 BSPs.  The submission and tracking
1245        process was captured as PR50.
1246        * ChangeLog: Removed bogus comment on edit of generated file.
1247        * acinclude.m4: Added gen405 BSP.

1282        256 meg to allow operation on boards with larger RAM sizes.
1283        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1284        vector function (mpc60x_vector_is_valid) instead of MPC750  specific
1285        function to allow operation on boards with CPUs other than the
1286        MPC750.

1298        shared/startup/bspstart.c, shared/vectors/vectors.S,
1299        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1300        "libbsp/powerpc/shared" BSP has been modified considerably with the
1301        goal to make it more flexible and reusable by other BSPs. The main
1302        strategies were: - eliminate hardcoded base addresses; devices use
1303        offsets and a BSP defined base address. - separate functionality
1304        into different files (e.g. reboot from inch.c to reboot.c) which can
1305        be overridden by a 'derived' BSP. - separate initialization code
1306        into separate files (e.g.  PCI bridge detection/initialization was
1307        separated from the more generic PCI access routines), also to make
1308        it easier for 'derived' BSPs to substitute their own initialization
1309        code. There are also a couple of enhancements and fixes: - IRQ
1310        handling code now has a hook for attaching a VME bridge. - OpenPIC
1311        is now explicitely initialized (polarities, senses). Eliminated the
1312        implicit assumption on the presence of an ISA PIC. - UART and
1313        console driver now supports more than 1 port. The current maximum of
1314        2 can easily be extended by enlarging a table (it would even be
1315        easier if the ISR API was not broken by design). - fixed polled_io.c
1316        so it correctly supports console on COM2 - fixed TLB invalidation
1317        code (start.S). - exception handler prints a stack backtrace. -
1318        added BSP_pciFindDevice() to scan the pci bus for a particular
1319        vendor/device/instance.

1323        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1324        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1325        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1326        direction of segments to memory regions may also have been
1327        addressed.  This was a sweep across all BSPs.
1328
13292001-04-08      Joel Sherrill <joel@OARcorp.com>
1330
1331        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

1334
1335        * shared/Makefile.am, shared/console/consoleIo.h,
1336        shared/include/bsp.h: These modifications are part of the conversion
1337        of the mpc8xx CPU to the "new exception processing model."
1338        * configure.in, motorola_powerpc/Makefile.am,
1339        motorola_powerpc/configure.in: These modifications are in support of
1340        switching the mpc8xx to the use the "new exception processing
1341        model."

13522000-11-01      Joel Sherrill <joel@OARcorp.com>
1353
1354        * shared/startup/bspstart.c: assoc.h, error.h, libio_.h, libio.h,
1355        and libcsupport.h moved from libc to lib/include/rtems and now must
1356        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1357        while doing this.
1358
13592000-10-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

1365
1366        * shared/startup/linkcmds: Added lines so DWARF debug information
1367        would be available.  Otherwise gdb complains that the offsets for
1368        the debug info are incorrect and doesn't load the files.
