|
|
|
| 21 |
|
|
* include/flash.h: Add a comment about the obvious: the flash
|
| 22 |
|
|
caching macros should be called with interrupts disabled.
|

| 24 |
|
|
2002-01-23 Jonathan Larmour
|
| 25 |

|
|
* cdl/io_flash.cdl: Add CYGPKG_IO_FLASH_BLOCK_DEVICE and

|
| 35 |
|
|
* src/flash.c : Modified flash_verify_addr, flash_erase,
|
| 36 |
|
|
flash_lock and flash_unlock to to work properly when the location
|
| 37 |
|
|
of the flash in the memory map is at the very top of the address
|
| 38 |
|
|
space. We check and handle values that may overflow.

|
|

|
|
* src/flash.c (flash_erase): Don't call hardware layer if block
|
| 43 |
|
|
appears to be already erased [faster and less wear & tear].

|
|
2001-06-19 Hugo Tyson
|
| 93 |
|
|
|
| 94 |
|
|
* src/flash.c (flash_program): Only verify program with memcmp if
|
| 95 |
|
|
the status code suggests the programming went OK so far.
|
| 96 |
|
|
Otherwise all errors become verify errors.
|
| 97 |
|
|
|
| 98 |
|
|
(flash_init): Fix bug in removal of dependency of printf(). The
|
| 99 |
|
|
pointer was not initialized until after the call into the driver.

|
| 123 |
|
|
to control whether or not to perform extra verification of flash
|
| 124 |
|
|
programming.

| 125 |
|
|
* src/flash.c (flash_program): No verification unless
|

|
|
|
| 139 |
|
|
* src/flash.c (flash_program):
|
| 140 |
|
|
* include/flash.h: Add support for [StrataFLASH] buffered writes.
|
| 141 |
|
|
This requires knowledge of the device write buffer size [saved].
|
| 142 |
|
|
|
| 143 |
|
|
2001-03-01 Gary Thomas
|
| 144 |
|
|
|
| 145 |
|
|
* src/flash.c:
|
| 146 |
|
|
* include/flash.h: Allow platform to define pre/post routines
|
| 147 |
|
|
to enable/disable device access. These may be required, e.g.
|
| 148 |
|
|
to turn on some voltage, etc.
|
| 149 |
|
|
|
| 150 |
|
|
2001-02-23 Jesper Skov
|
| 151 |
|
|
|
| 152 |
|
|
* include/flash.h: HAL_FLASH_CACHES_WANT_OPTIMAL replaced with
|
| 153 |
|
|
(opposite sense) HAL_FLASH_CACHES_OLD_MACROS.
|
| 154 |
|
|
|
| 155 |
|
|
* src/flash.c (__anonymizer): Use to force the compiler to use
|
| 156 |
|
|
jumps instead of branches.
|
| 157 |
|
|
|
| 158 |
|
|
2001-02-22 Jesper Skov
|
| 159 |
|
|
|
| 160 |
|
|
* include/flash_dev.h: Added. Contains macros and definitions
|
| 161 |
|
|
common to all (new style) flash device drivers.
|
| 162 |
|
|
|
| 163 |
|
|
* include/flash.h: Added two new error codes.
|
| 164 |
|
|
* cdl/io_flash.cdl: Added CYGHWR_IO_FLASH_DEVICE_IN_RAM.
|
| 165 |
|
|
* src/flash.c: Made functions respect
|
| 166 |
|
|
CYGHWR_IO_FLASH_DEVICE_IN_RAM and jump directly to the code
|
| 167 |
|
|
instead of copying it around.
|
| 168 |
|
|
(__arm_broken): Work around problem with ARM tools.
|
| 169 |
|
|
|
| 170 |
|
|
2001-02-06 Hugo Tyson
|
| 171 |
|
|
|
| 172 |
|
|
* src/flash.c (flash_erase): Add an additional argument to the
|
| 173 |
|
|
call into the driver, being the blocksize (as discovered). This
|
| 174 |
|
|
allows a gross check for actual erase in some drivers. Those that
|
| 175 |
|
|
don't use it, it's harmless - after all, this is an API by trust.
|
| 176 |
|
|
|
| 177 |
|
|
2000-12-06 Jesper Skov
|
| 178 |
|
|
|
| 179 |
|
|
* src/flash.c (flash_dev_query): Added. Allows reloc/cache magic
|
| 180 |
|
|
to be removed from device drivers (eventually). Also fixed some
|
| 181 |
|
|
warnings, and made function references use char[] instead of just
|
| 182 |
|
|
char to prevent MIPS compiler from messing up.
|
| 183 |
|
|
|
| 184 |
|
|
* include/flash.h: Added FLASH_ERR_DRV_VERIFY and flash_dev_query.
|
| 185 |
|
|
|
| 186 |
|
|
2000-11-27 Jesper Skov
|
| 187 |
|
|
|
| 188 |
|
|
* src/flash.c: Do all flash access inside properly
|
| 189 |
|
|
cache-controlled region.
|
| 190 |
|
|
* include/flash.h: Cache definitions.
|
| 191 |
|
|
|
| 192 |
|
|
2000-11-17 Jesper Skov
|
| 193 |
|
|
|
| 194 |
|
|
* src/flash.c: Added debug mode, allowing device driver to use printf.
|
| 195 |
|
|
|
| 196 |
|
|
2000-11-16 Jesper Skov
|
| 197 |
|
|
|
| 198 |
|
|
* src/flash.c: Added suspend error messages.
|
| 199 |
|

| 201 |
|
|
2000-09-01 Hugo Tyson
|
| 202 |
|
|
|
| 203 |
|
|
* include/flash.h:
|
| 204 |
|
|
* src/flash.c: CYGHWR_IO_FLASH_BLOCK_LOCKING is an interface, so
|
| 205 |
|
|
it's always defined; look for > 0 instead.
|
| 206 |
|
|
|
| 207 |
|
|
2000-08-28 Gary Thomas
|
| 208 |
|
|
|
| 209 |
|
|
* src/flash.c:
|
| 210 |
|
|
* include/flash.h:
|
| 211 |
|
|
* cdl/io_flash.cdl: Support block locking (optional by hardware).
|
| 212 |

|
| 213 |
|
|
2000-08-22 Hugo Tyson
|
| 214 |
|
|
|
| 215 |
|
|
* src/flash.c (flash_program): Add HAL_ICACHE_DISABLE/ENABLE pairs
|
| 216 |
|
|
around calls to RAM copy of programming/erasing function - this is
|
| 217 |
|
|
necessary to get reliable operation on EBSA285 and similar.
|
| 218 |
|
|
Otherwise, what is in the instruction cache might be run instead.
|
| 219 |
|
|
|
| 220 |
|
|
2000-08-14 Gary Thomas
|
| 221 |
|

|
|
|
| 226 |
|
|
2000-07-29 Gary Thomas
|
| 227 |
|
|
|
| 228 |
|
|
* include/flash.h:
|
| 229 |
|
|
* src/flash.c (flash_get_block_info): New function.
|
| 230 |
|
|
(flash_program): Program in block_size chunks as much as possible.
