3        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Add use
4        of bsp_get_work_area() in its own file and rely on BSP Framework to
5        perform more initialization.
6        * shared/startup/bspgetworkarea.c: New file.

82008-09-10      Joel Sherrill <joel.sherrill@oarcorp.com>
9
10        * shared/startup/bspstart.c: Review of all bsp_cleanup()
11        implementations. In this phase, all prototypes were removed from
12        bsp.h and empty implementations were removed and made to use the
13        shared stub.
14
152008-09-08      Joel Sherrill <joel.sherrill@oarcorp.com>
16
17        * acinclude.m4: Add tqm8xx.
18
192008-09-08      Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
20
21        * tqm8xx: New BSP.
22
232008-09-06      Ralf Corsépius <ralf.corsepius@rtems.org>
24
25        * shared/irq/irq.c: Convert to "bool".
26
272008-09-05      Joel Sherrill <joel.sherrill@OARcorp.com>
28
29        * shared/clock/clock.c: The Shared Memory Driver no longer requires the
30        special IOCTL in Clock_control. This was a hack which has existed
31        since before the Classic API Timer Manager was implemented. All
32        implementations of and references to Clock_control were removed.
33
342008-09-05      Ralf Corsépius <ralf.corsepius@rtems.org>
35
36        * shared/console/inch.c: Convert to "bool".
37
382008-08-28      Till Straumann <strauman@slac.stanford.edu>
39
40        * shared/vme/vme_universe.c: added implementation for
41        BSP_VMEResetBus().
42
432008-08-20      Ralf Corsépius <ralf.corsepius@rtems.org>
44
45        * shared/flash/flash.c, shared/irq/irq_init.c: Add missing
46        prototypes.
47        * shared/showbats.c, shared/console/inch.c, shared/irq/irq_init.c,
48        shared/pci/detect_raven_bridge.c, shared/startup/bspstart.c,
49        shared/startup/zerobss.c, shared/vme/vmeconfig.c,
50        startup/exit.c: Add missing prototypes.
51
522008-08-19      Sebastian Huber <sebastian.huber@embedded-brains.de>
53
54        * shared/clock/clock.c: Fixed warnings.
55
562008-07-18      Sebastian Huber <sebastian.huber@embedded-brains.de>
57
58        * shared/clock/clock.c: Update due to powerpc-utilty.h changes.
59
602008-07-14      Sebastian Huber <sebastian.huber@embedded-brains.de>
61
62        * mpc55xxevb: New BSP.
63
642008-07-14      Thomas Doefler <Thomas.Doerfler@embedded-brains.de>
65        * haleakala: added new BSP
66
672008-07-11      Sebastian Huber <sebastian.huber@embedded-brains.de>
68
69        * ep1a/startup/bspstart.c, mvme3100/startup/bspstart.c,
70        mvme5500/startup/bspstart.c, psim/startup/bspstart.c,
71        shared/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
72        used to store the interrupt disable mask.  See bootcard.c and
73        ppc_exc_initialize() for default initialization.
74
75        Update to new exception initialization routine ppc_exc_initialize().
76        The exception low level code has changed, see libcpu/powerpc/ChangeLog.
77
78        * gen5200/startup/bspstart.c, mbx8xx/startup/bspstart.c,
79        mpc8260ads/startup/bspstart.c, ss555/startup/bspstart.c,
80        virtex/startup/bspstart.c: The usage of SPRG0 as changed.  It is now
81        used to store the interrupt disable mask.  See bootcard.c for default
82        initialization.
83
842008-07-10      Till Straumann <strauman@slac.stanford.edu>
85
86        * shared/flash/spansionFlash.c: removed "m" memory
87        operands.
88
892008-07-09      Sebastian Huber <sebastian.huber@embedded-brains.de>
90
91        * shared/clock/clock.c: Alternative clock driver.  Uses exception handler
92        directly.  Supports special variants for Book E and e300 cores.  For
93        standard decrementer CPUs the new decrementer value is calculated with
94        reference to a time base so that a time drift is avoided.
95
962008-07-01      Joel Sherrill <joel.sherrill@oarcorp.com>
97
98        * shared/uboot_getenv.c: New file.
99
1002008-06-02      Joel Sherrill <joel.sherrill@oarcorp.com>
101
102        * shared/startup/panic.c: Convention calls for leading underscore on
103        private RTEMS variables.
104
1052008-05-23      Till Straumann <strauman@slac.stanford.edu>
106
107        * shared/startup/pretaskinghook.c: removed declaration
108        of BSP_vme_config() (which is already declared in
109        <bsp/VME.h>. Removed test for NULL-ness of BSP_vme_config;
110        gcc doesn't seem to understand that the linker may
111        define this to be NULL... Silences a compiler warning
112        (and users can always provide an empty routine).
113
1142008-05-22      Till Straumann <strauman@slac.stanford.edu>
115
116        * shared/startup/linkcmds, shared/startup/zerobss.c:
117        introduced '__bss_end'; assuming that __rtems_end
118        coincides with the end of .bss for the purpose of
119        zeroing .bss is very dangerous.
120
1212008-05-22      Joel Sherrill <joel.sherrill@OARcorp.com>
122
123        * shared/console/console.c: Fix typo.
124
1252008-05-22      Joel Sherrill <joel.sherrill@oarcorp.com>
126
127        * shared/console/console.c: Remove explicit switch and call
128        termios_baud_to_number().
129
1302008-05-15      Joel Sherrill <joel.sherrill@OARcorp.com>
131
132        * shared/startup/pretaskinghook.c: Add capability for bootcard.c BSP
133        Initialization Framework to ask the BSP where it has memory for the
134        RTEMS Workspace and C Program Heap. These collectively are referred
135        to as work area. If the BSP supports this, then it does not have to
136        include code to split the available memory between the two areas.
137        This reduces the amount of code in the BSP specific bspstart.c file.
138        Additionally, the shared framework can initialize the C Library, call
139        rtems_debug_enable(), and dirty the work area memory. Until most/all
140        BSPs support this new capability, if the BSP supports this, it should
141        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
142        When the transition is complete, this autoconf macro can be removed.
143
1442008-05-12      Joel Sherrill <joel.sherrill@OARcorp.com>
145
146        * shared/startup/bspstart.c: Refactored and renamed initialization
147        routines to rtems_initialize_data_structures,
148        rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
149        rtems_initialize_start_multitasking. This opened the sequence up so
150        that bootcard() could provide a more robust and flexible framework
151        which is easier to explain and understand. This also lays the
152        groundwork for sharing the division of available memory between the
153        RTEMS workspace and heap and the C library initialization across all
154        BSPs.
155
1562008-03-21      Till Straumann <strauman@slac.stanford.edu>
157
158        * shared/console/uart.c: In IRQ driven mode also
159        keep reading chars while they are available (fifo
160        could be enabled).
161
1622008-03-19      Till Straumann <strauman@slac.stanford.edu>
163
164        * shared/console/console.c, shared/console/uart.c,
165        shared/console/uart.h: added support for task-driven
166        console.
167
1682008-03-19      Till Straumann <strauman@slac.stanford.edu>
169
170        * shared/startup/pretaskinghook.c: install pointer
171        to rtems_malloc_sbrk_helpers_table. This (and derived)
172        BSPs rely on sbrk delivering even the first/initial
173        chunk of memory.
174
1752008-03-03      Joel Sherrill <joel.sherrill@OARcorp.com>
176
177        * shared/startup/linkcmds: Add wildcard to gcc_except_table section so
178        programs compiled with gcc 4.3.x can link.
179
1802008-02-19      Ralf Corsépius <ralf.corsepius@rtems.org>
181
182        * gen405: Remove (Abandoned).
183        * helas403: Remove (Abandoned).
184        * acinclude: Regenerate.
185
1862007-12-14      Joel Sherrill <joel.sherrill@oarcorp.com>
187
188        * acinclude.m4, gen5200/irq/irq.c, gen5200/startup/bspclean.c: Add
189        mvme3100.
190
1912007-12-11      Joel Sherrill <joel.sherrill@OARcorp.com>
192
193        * shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
194        copies of the Configuration Table. Use the RTEMS provided accessor
195        macros to obtain configuration fields.
196
1972007-12-10      Till Straumann <strauman@slac.stanford.edu>
198
199        * Makefile.am, start/preload.S: moved preload.S
200        to ../shared/start.
201
2022007-12-10      Till Straumann <strauman@slac.stanford.edu>
203
204        * shared/irq/irq_asm.S, shared/vectors/vectors.h:
205        renamed ASM_BOOKE_PIT_VECTOR to ASM_BOOKE_DEC_VECTOR
206        to be closer to 'official' nomenclature.
207
2082007-12-10      Till Straumann <strauman@slac.stanford.edu>
209
210        * shared/openpic/openpic.c: fixed wrong register
211        address in openpic_gettimer().
212
2132007-12-10      Till Straumann <strauman@slac.stanford.edu>
214
215        * shared/motorola/vpd.c, shared/motorola/vpd.h:
216        added code (originally developed for 'beatnik')
217        to read MotLoad VPD data from i2c eeprom.
218
2192007-12-10      Till Straumann <strauman@slac.stanford.edu>
220
221        * shared/vectors/README.deprecated, shared/irq/README.deprecated:
222        added READMEs stating that certain files should not be
223        copy/paste/modified when creating new BSPs. New BSPs
224        are encouraged to use the new library under
225        libcpu/powerpc/new-exceptions/bspsupport.
226
2272007-12-10      Till Straumann <strauman@slac.stanford.edu>
228       
229        * shared/vectors/vectors_entry.S, motorola_powerpc/bsp_specs,
230        shared/start/vectors_entry.S: moved vectors_entry.S to
231        'start' subdir and made a start file rather than
232        element of vectors.rel (it should always be linked but
233        won't if it is the sole member of vectors.rel).
234
2352007-12-08      Till Straumann <strauman@slac.stanford.edu>
236
237        * shared/vme/vme_universe.c: fixed wrong initialization
238        routine when using Tsi148 driver.
239
2402007-12-08      Till Straumann <strauman@slac.stanford.edu>
241
242        * Makefile.am: merged shared/vme/vme_universe.c and
243        shared/vme/vme_universe_dma.c into one file.
244        Added support for Tsi148 driver (DMA).
245
2462007-12-08      Till Straumann <strauman@slac.stanford.edu>
247
248        * shared/vme/VMEConfig.h, shared/vme/vme_universe.c:
249        added support for Tsi148 bridge; BSP can define which
250        bridge driver to use from VMEConfig.h.
251        Added 'err' macro parameter to BSP_VME_INSTALL_IRQ_MGR(err)
252        macro so that an error status can be passed back.
253
2542007-12-08      Till Straumann <strauman@slac.stanford.edu>
255
256        * irq_supp.h: was moved from shared/irq to
257        libcpu/powerpc/new-exceptions/bspsupport.
258
2592007-12-08      Till Straumann <strauman@slac.stanford.edu>
260
261        * ep1a/irq/irq.c, gen5200/irq/irq.c, gen83xx/irq/irq_init.c,
262        mbx8xx/irq/irq.c, mpc8260ads/irq/irq.c, mvme5500/irq/irq.c,
263        psim/irq/no_pic.c, score603e/irq/irq.c, shared/irq/irq_supp.h,
264        shared/irq/openpic_i8259_irq.c, virtex/irq/irq_init.c:
265        let C_dispatch_irq_handler() return zero to indicate to
266        low-level exception handling code that the exception
267        was handled (not used yet).
268
2692007-12-08      Till Straumann <strauman@slac.stanford.edu>
270
271        *shared/irq/irq_supp.h: removed cpp test for
272        BSP_SHARED_HANDLER_SUPPORT; BSPs using irq_supp.h
273        *must* implement shared handlers.
274
2752007-12-06      Till Straumann <strauman@slac.stanford.edu>
276
277        * shared/openpic/openpic.c, shared/openpic/openpic.h:
278        added routines to set timer period and interupt mask
279        and to read current count.
280
2812007-12-06      Till Straumann <strauman@slac.stanford.edu>
282
283        * virtex/irq/irq_init.c: use new ASM_xxx_VECTOR names.
284
2852007-12-06      Till Straumann <strauman@slac.stanford.edu>
286
287        * shared/vectors/vectors_init.c: replaced
288        switch ( current_ppc_cpu ) { } check by feature check.
289
2902007-12-06      Till Straumann <strauman@slac.stanford.edu>
291
292        * shared/irq/irq_asm.S, shared/vectors/vectors.S:
293        Replaced use of hardcoded PPC_EXC_MSR_BITS by a
294        run-time method to determine these bits (use settings
295        effective before exception occurred).
296        Replaced use of hardcoded ASM_VECTORS_CRITICAL by
297        'bsp_raw_vector_is_405_critical' variable.
298
2992007-12-05      Till Straumann <strauman@slac.stanford.edu>
300
301        * shared/irq/irq_supp.h: removed stray '*/'. Removed
302        inclusion of <stdlib.h> which is unnecessary and broke
303        if_dc in an obscure way (due to malloc/free redefinition
304        in the networking code).
305
3062007-12-05      Till Straumann <strauman@slac.stanford.edu>
307
308        * shared/irq/irq_asm.S, shared/vectors/vectors.S,
309        shared/vectors/vectors.h, shared/vectors/vectors_init.c:
310        Converted exception vector names to new ones
311        (qualified by <cpu_type> if non-std ppc exceptions).
312
313
3142007-12-04      Till Straumann <strauman@slac.stanford.edu>
315
316        * shared/startup/bspstart.c: export BSP_commandline_string
317        variable.
318
3192007-12-04      Till Straumann <strauman@slac.stanford.edu>
320
321        * shared/flash/flash.c: added lazy init of driver
322        from BSP_flashWriteFile().
323
3242007-12-04      Joel Sherrill <joel.sherrill@OARcorp.com>
325
326        * shared/startup/bspstart.c: Move interrupt_stack_size field from CPU
327        Table to Configuration Table. Eliminate CPU Table from all ports.
328        Delete references to CPU Table in all forms.
329
3302007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
331
332        * shared/irq/irq.c: Spacing.
333
3342007-12-03      Joel Sherrill <joel.sherrill@OARcorp.com>
335
336        * shared/startup/bspstart.c: Moved most of the remaining CPU Table
337        fields to the Configuration Table. This included pretasking_hook,
338        predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
339        extra_mpci_receive_server_stack, stack_allocate_hook, and
340        stack_free_hook. As a side-effect of this effort some multiprocessing
341        code was made conditional and some style clean up occurred.
342
3432007-12-03      Joel Sherrill <joel.sherrill@oarcorp.com>
344
345        * shared/irq/irq.c, shared/irq/irq_supp.h: Correct conditionals and
346        includes.
347
3482007-12-02      Till Straumann <strauman@slac.stanford.edu>
349
350        * shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
351        shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
352        openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
353        0/1 if irq was disabled/enabled prior to disabling.
354        irq_supp.h now exports a inline helper routine for scanning
355        a list of shared handlers; to be used by PIC drivers.
356
3572007-12-02      Till Straumann <strauman@slac.stanford.edu>
358
359        * shared/openpic/openpic.c shared/openpic/openpic.h,
360        shared/irq/irq_init.c: added more parameters to
361        openpic_init() so that more details of the configuration
362        can be overridden/set from the BSP. Moved setup of
363        the EPIC-specific EOI delay from BSP code into openpic_init()
364        using the new 'epic_freq' parameter.
365
3662007-12-02      Till Straumann <strauman@slac.stanford.edu>
367        * shared/openpic/openpic.c, shared/openpic/openpic.h:
368        - eliminated conditional compilation (#ifdef mpc8240)
369          The difference in register-layout between the EPIC
370          and the std. openPIC is handled by an offset parameter
371          which can be set at run-time (initialization) with
372          a new routine 'openpic_set_src_offset()'.
373        - allow BSP to define symbol BSP_OPEN_PIC_BIG_ENDIAN
374          which builds the driver for big-endian register access
375          (mpc8540).
376        - openpic_disable_irq() now returns the old state so
377          that it can be restored later.
378
3792007-12-01      Till Straumann <strauman@slac.stanford.edu>
380
381        * shared/irq/openpic_i8259_irq.c:
382        - conditionally define 'irq_mask_or_tbl' only if
383          BSP_PCI_ISA_BRIDGE_IRQ is defined.
384        - use _ISR_Get_level() / _ISR_Set_level() for re-enabling
385          interrupts rather than messing with MSR directly;
386          these macros:
387            o implement compiler memory barrier
388                o will handle multiple levels (e500 'critical' interrupts)
389                  if they are ever supported.
390        - decrementer irqs are also shareable - added list traversal.
391
3922007-12-01      Till Straumann <strauman@slac.stanford.edu>
393
394        * shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
395        is set. The shared irq manager supports shared interrupts
396        (but requires also that the PIC-driver supports them by
397        traversing the list of shared handlers).
398        Declare C_dispatch_irq_handler() which must be defined
399        (like the other routines declared in this header) by the

450        shared/irq/irq_supp.h (added):
451        Removed 'is_processor_irq()' from irq.c; the BSP routines
452        BSP_enable_irq_at_pic()/BSP_disable_irq_at_pic() are required
453        to ignore processor irqs anyways. Removed
454        all BSP-defined constants from irq.c. This makes irq.c (almost)
455        binary-compatible among BSPs (ultimate goal is making 'shared'
456        a library).
457        Added a header (irq_supp.h) defining the interface between
458        the generic interrupt manager (irq.c) and the routines it
459        requires to be supplied by the BSP (eventually, these
460        should go into rtems/irq.h).

465        of ASM_IRQ_VECTOR_BASE; this symbol was only use to
466        initialize the irqBase member of the rtems_irq_global_settings
467        struct. However, irqBase is an rtems_irq_symbolic_name,
468        so using BSP_LOWEST_OFFSET is more appropriate.

482        for some intel + spansion flash chips (as found on mvme5500,
483        mvme6100 and mvme3100 boards).
484        A more appopriate place would probably be libchip but
485        I don't know if the API is acceptable and if the implementation
486        is generic enough (e.g., no CFI support) so I leave it here
487        for now.

494
495        * shared/console/uart.c: when draining UART during
496        initialization (wait for possible printk() activity
497        to finish) look at TEMT (fifo, holding-reg and shift-reg)
498        rather than THRE (fifo, holding-reg only). This resolved
499        some scrambled output issues for me.
500
501        Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
502        value then the driver interprets the modulus as a speed value
503        and uses the current setting of the divisor to compute the
504        clock speed (BSPBaseBaud). This is useful if you have a board
505        that you know is initialized e.g., to 9600 but you
506        don't know the clock speed.

1192        PPCbug. Also turn off mmu/caches for the bootstrap phase, which
1193        seems to cause trouble with the 603.  The cpu init functions in the
1194        bsp get all that stuff going properly.

1341        256 meg to allow operation on boards with larger RAM sizes.
1342        * shared/vectors/vectors_init.c: Modified to call 'generic' powerpc
1343        vector function (mpc60x_vector_is_valid) instead of MPC750  specific

1357        shared/startup/bspstart.c, shared/vectors/vectors.S,
1358        shared/vectors/vectors.h, shared/vectors/vectors_init.c: Per PR216,
1359        "libbsp/powerpc/shared" BSP has been modified considerably with the
1360        goal to make it more flexible and reusable by other BSPs. The main
1361        strategies were: - eliminate hardcoded base addresses; devices use
1362        offsets and a BSP defined base address. - separate functionality
1363        into different files (e.g. reboot from inch.c to reboot.c) which can
1364        be overridden by a 'derived' BSP. - separate initialization code
1365        into separate files (e.g.  PCI bridge detection/initialization was
1366        separated from the more generic PCI access routines), also to make
1367        it easier for 'derived' BSPs to substitute their own initialization
1368        code. There are also a couple of enhancements and fixes: - IRQ
1369        handling code now has a hook for attaching a VME bridge. - OpenPIC
1370        is now explicitely initialized (polarities, senses). Eliminated the
1371        implicit assumption on the presence of an ISA PIC. - UART and
1372        console driver now supports more than 1 port. The current maximum of
1373        2 can easily be extended by enlarging a table (it would even be
1374        easier if the ISR API was not broken by design). - fixed polled_io.c
1375        so it correctly supports console on COM2 - fixed TLB invalidation
1376        code (start.S). - exception handler prints a stack backtrace. -
1377        added BSP_pciFindDevice() to scan the pci bus for a particular
1378        vendor/device/instance.

1382        * shared/startup/linkcmds: In support of gcc 3.1, added one of more
1383        of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*,
1384        .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*.  Spacing corrections and
1385        direction of segments to memory regions may also have been
1386        addressed.  This was a sweep across all BSPs.
1387
13882001-04-08      Joel Sherrill <joel@OARcorp.com>
1389
1390        * shared/startup/linkcmds: Per PR170, PR171, and PR172 add .eh_frame

1393
1394        * shared/Makefile.am, shared/console/consoleIo.h,
1395        shared/include/bsp.h: These modifications are part of the conversion
1396        of the mpc8xx CPU to the "new exception processing model."
1397        * configure.in, motorola_powerpc/Makefile.am,
1398        motorola_powerpc/configure.in: These modifications are in support of
1399        switching the mpc8xx to the use the "new exception processing

1414        and libcsupport.h moved from libc to lib/include/rtems and now must
1415        be referenced as <rtems/XXX.h>.   Header file order was cleaned up
1416        while doing this.
