3 3 * src/flashiodev.c (flashiodev_init): Assign
4 * src/flash.c (flash_init): Allow repeat calls change the function 4 CYG_DEVTAB_STATUS_BLOCK to status field of device table
5 used for printing. There are times you don't any output, eg you 5 entries. This causes devfs to call the right read/write
6 are downloading am image over the serial port. 6 operations.

8 2008-06-10 Jonathan Larmour <jifl@eCosCentric.com>
9
10 * tests/flashdev.c (FLASH_TEST_LENGTH): Reduce to a
11 multiple of 0x20000 as some flash parts (especially if
12 they are in fact multiple chips in parallel) have that
13 block size.
14 Try opening jffs2test FIS partition if flashtest doesn't exist.
15
16 2007-05-14 Jonathan Larmour <jifl@eCosCentric.com>

28 cyg_flash_errmsg. And some warning cleanups.
29
30 * src/flashiodev.c (flashiodev_lookup): Correct misplaced else
31 with respect to #ifdefs. Fix for bug 1000355.
32
33 2006-12-18 Nick Garnett <nickg@ecoscentric.com>
34
35 * src/flash_legacy.h (FLASH_Enable, FLASH_Disable): Add casts to
36 these macros since the calls in the source don't present the right
37 types. This is mainly an exercise in suppressing compiler
38 warnings.
39
40 2006-12-07 Nick Garnett <nickg@ecoscentric.com>
41
42 * tests/flashdev.c (cyg_start): Fix bug, b.offset should be
43 initialized to 0. Until now it was some random value on the stack,
44 why this has never bitten us before is a mystery.

58 if this is used with one of multiple flash devices in a
59 system where a different one does support locking.
60 (cyg_flash_devfn_unlock_nop): Ditto.
61

94 (cyg_start): Added tests for lock and unlock functions.
95
96 2005-09-28 Jonathan Larmour <jifl@eCosCentric.com>
97
98 * src/flash.c (flash_sort_and_check): Allow for Flash
99 device initialisation to fail, and thus not put this device
100 on the Flash device list.
101
102 2005-09-26 Bart Veer <bartv@ecoscentric.com>
103
104 * src/flash.c: put init flag into .bss rather than .data, avoids

130
131 * src/legacy_dev.c (legacy_flash_init): Assign flash_info.pf from
132 flash device field. Otherwise drivers try to call an invalid
133 address.
134 (legacy_flash_program): The last argument to flash_program_buf()
135 is not the block size but the programming buffer size.
136
137 2005-01-21 Jonathan Larmour <jifl@eCosCentric.com>
138
139 * doc/flash.sgml: Document Flash block devices.

148 pointer in cyg_io_flash_getconfig_erase_t.
149 * src/flash_legacy.h: Undef HAL_FLASH_CACHES_* macros if the HAL
150 supplied them and they're not needed.
151
152 * src/legacy_api.c (flash_errmsg): Was missing. Add.
153
154 * tests/flash1.c (cyg_start): Silence warning.
155
156 2004-12-02 Bart Veer <bartv@ecoscentric.com>
157
158 * include/flash_dev.h: now provides everything needed by flash
159 device drivers.
160
161 * include/flash_priv.h: removed, subsumed by flash_dev.h
162
163 * include/flash.h, src/flash.c, src/flashiodev.c,

165 Replace implicit #include's of <cyg/io/flash_priv.h> with explicit
166 #include's of <cyg/io/flash_dev.h>
167
168 2004-11-29 Bart Veer <bartv@ecoscentric.com>
169
170 * include/flash_priv.h, src/flash.c, src/legacy_dev.c: remove
171 hwr_map_error() from V2 drivers
172
173 * include/flash_priv.h, src/flash.c, src/legacy_dev.c: provide
174 dummy init/query/lock/unlock functions for use by device drivers
175 which do not support/need this functionality. Export the
176 anonymizer function.
177
178 2004-11-28 John Dallaway <jld@ecoscentric.com>
179
180 * doc/flash.sgml: Fix minor SGML tag problems.
181
182 2004-11-28 Bart Veer <bartv@ecoscentric.com>
183
184 * src/flash.c (flash_sort_and_check): previous patch would have
185 resulted in init failure if only one device initialized.
186 (cyg_flash_get_info): handle per-device init flag
187
188 2004-11-25 Andrew Lunn <andrew.lunn@ascom.ch>
189
190 * src/flash.c (flash_sort_and_check): Don't add devices which
191 failed to initialise onto the list. Don't bother sorting the
192 list if its empty or only has one entry.

194 don't both checking the init flag.
195
196 2004-11-24 Bart Veer <bartv@ecoscentric.com>
197
198 * cdl/io_flash.cdl, src/flash.c, src/flash_legacy.h,
199 src/legacy_dev.c: add support for V2 drivers which can take care

203 being used.
204 * Merge from flash V2 branch
205
206 2004-11-22 Bart Veer <bartv@ecoscentric.com>
207
208 * src/legacy_dev.c: remove .2ram attributes. These functions do
209 not manipulate the hardware, there is no need for them to live in
210 ram rather than flash
211 * include/flash_priv.h, src/legacy_dev.c: clean up the interface
212 between the generic flash code and the device drivers
213 * include/flash_priv, src/flash_legacy.h, src/flash.c,
214 src/legacy_dev.c: move cache stuff andother legacy macros

220 2004-11-21 Bart Veer <bartv@ecoscentric.com>
221
222 * src/flash.c, include/flash_priv.h, cdl/io_flash.h: optimize
223 for the case of a single flash device.
224 * include/flash.h, src/flash.c, doc/flash.sgml: remove
225 cyg_flash_code_overlaps()
226 * include/flash_priv.h, include/flash.h:
227 CYGSEM_IO_FLASH_LEGACY_DEVICE_API has been removed, test
228 CYGHWR_IO_FLASH_DEVICE_LEGACY instead
229 * cdl/io_flash.cdl: lots of clean-ups
230 * src/legacy_dev.c (legacy_flash_read): only needed if the
231 underlying legacy driver required indirect reads.

233 macros, to cut down on the #ifdef's in the main code
234
235 2004-11-20 Bart Veer <bartv@ecoscentric.com>
236
237 * cdl/io_flash.cdl, src/flash.c(cyg_flash_read): add an interface
238 for hardware which requires indirect reads, and suppress
239 unnecessary code if direct reads are always available.
240 * src/flash.c: rearrange loops to avoid address comparisons, which
241 tend to go wrong if the flash is at the end of the address space
242
243 2004-10-06 Andrew Lunn <andrew.lunn@ascom.ch>
244
245 * src/legacy_dev.c (legacy_flash_init): The end is the size plus
246 the start.
247
248 2004-09-30 Savin Zlobec <savin@elatec.si>
249
250 * src/flash.c: Offset into the block is not calculated correctly
251 when the flash start is not aligned on a flash block.
252 * src/legacy_dev.c (legacy_flash_read): Fixed typo.
253
254 2004-09-14 Andrew Lunn <andrew.lunn@ascom.ch>
255
256 * src/flash.c (cyg_flash_init): Add assert checking that the
257 end address matches the block information.
258 * src/legacy_dev.c (legacy_flash_init): Ensure that the end
259 address is the last valid address, not the first invalid address.
260
261 2004-09-09 Andrew Lunn <andrew.lunn@ascom.ch>
262
263 * src/flash.c: Support flash blocks of arbitary size. The
264 DataFlash devices for example have block of 528 bytes.
265
266 2004-08-21 Andrew Lunn <andrew.lunn@ascom.ch>
267
268 * removed the functions cyg_flash_get_limits and
269 cyg_flash_get_block_info. Reimplemented the legacy functions
270 that depended on them and flashiodev.c
271
272 2004-08-19 Andrew Lunn <andrew.lunn@ascom.ch>
273
274 * src/flashiodev.c Ordering problem again. If an invalid name is
275 configured the lookup would fail and it then was impossible to do
276 a cyg_io_config_set. Lookup cannot fail because the name does not
277 exist in FIS.
278
279 2004-08-13 Andrew Lunn <andrew.lunn@ascom.ch>
280
281 * src/flash.c: Make the flock lock/unlock code compile without
282 warnings.
283 * src/flashiodev.c (flashiodev_lookup): Only initialize the device
284 if we have not already been initialized via cyg_set_config().
285 This stopped redboots mount -f working.
286
287 2004-08-09 Andrew Lunn <andrew.lunn@ascom.ch>
288
289 * src/flashiodev.c (flashiodev_lookup): Moved most of the
290 flashiodev_init into this new function. This fixed the ordering
291 issue with redboot startup. When doing a FIS name lookup in
292 flashiodev_init, redboot was not yet nitialised so lookup
293 failed. Moving this into flashiodev_lookup solves this problem.
294 Its now possible for redboot to mount the jffs2 filesystem with
295 -d /dev/flash1.
296
297 2004-08-06 Andrew Lunn <andrew.lunn@ascom.ch>
298
299 * src/flashiodev.c: Fix typo in macro and configuration options
300
301 2004-08-05 Andrew Lunn <andrew.lunn@ascom.ch>
302
303 * src/flash.c: Major rewrite to implement a new API
304 * src/legacy_api.c: Support the legacy API
305 * src/legacy_drv.c: Support the legacy driver API
306 * src/flashiodev.c: Support the new API and multiple devices
307 * include/flash_priv.h: Interface devices should use
308 * cdl/io_flash.cdl: Updates for new interface and multiple devices.
309
16 2004-09-05 Mark Salter <msalter@redhat.com> 310 2004-09-05 Mark Salter <msalter@redhat.com>
17 311
18 * doc/flash.sgml: Fix unbalanced <PARA>s. 312 * doc/flash.sgml: Fix unbalanced <PARA>s.
19 313

48 342
49 * cdl/io_flash.cdl: 343 * cdl/io_flash.cdl:
50 * include/flash.h: Remove CYGNUM_FLASH_WORKSPACE_SIZE cdl option. 344 * include/flash.h: Remove CYGNUM_FLASH_WORKSPACE_SIZE cdl option.
51 345
52 2003-11-24 Roland Caßebohm <roland.cassebohm@visionsystems.de> 346 2003-11-24 Roland Caßebohm <roland.cassebohm@visionsystems.de>
53 347
54 * src/flashiodev.c (flashiodev_bwrite): Use flash_read rather than 348 * src/flashiodev.c (flashiodev_bwrite): Use flash_read rather than
55 directly doing a memcpy. 349 directly doing a memcpy.
56 350
