* sf: kick watchdog when pollingPatrick Sestier2011-06-01-0/+3
| | | | | | | | The status polling can take a while, so make sure we kick the watchdog after each successful poll. Signed-off-by: Patrick Sestier <psestier@mircom.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | No need for these to be exported as they are only accessed indirectly via function pointers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: sst: setup read funcMike Frysinger2011-04-12-0/+1
| | | | | | The previous unification patch missed setting up the sst read func. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: add struct spi_flash.sector_size parameterRichard Retanubun2011-04-12-64/+28
| | | | | | | | | | | | | | | This patch adds a new member to struct spi_flash (u16 sector_size) and updates the spi flash drivers to start populating it. This parameter can be used by spi flash commands that need to round up units of operation to the flash's sector_size. Having this number in one place also allows duplicated code to be further collapsed into one common location (such as erase parameter and the detected message).

* sf: atmel: undo unification of status pollingMike Frysinger2011-04-11-2/+29
| | | | | | | | The AT45 flashes are completely different (at the command set and status register level) from all other SPI flashes, so we can't unify their logic with common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* sf: unify status polling for ready bitMike Frysinger2011-04-11-283/+81
| | | | | | | | All of the spi flash drivers implement the status register polling for detecting the device ready state, so unify them all in a new helper function -- spi_flash_wait_ready. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: unify read/write helpersMike Frysinger2011-04-11-48/+19
| | | | | | | These functions largely do the same exact thing, so unify them all into one basic function. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* sf: ramtron: new spi fram driverReinhard Meyer2010-11-10-0/+329
| | | | | | | Supports most types that support Read-Id and the FM25H20. Signed-off-by: Reinhard Meyer <u-boot@emk-elektronik.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: turn probe switch into a lookup tableReinhard Meyer2010-10-12-44/+82
| | | | | | | | | | This allows for arbitrarily long manufacturer ids following the JEDEC standard of 0x7f continuation bytes. It also makes adding new entries easier as it's just one element in an array. The downside is that it increases code size a bit, but we're talking ~50 bytes.

* sf: spansion: add support for S25FL032P partsDavid Jander2010-10-06-0/+9
| | | | | | | | This patch introduces an extra mask-field in spansion_spi_flash_params to support flash chips with 1-byte extended ID (like the S25FL032P). Signed-off-by: David Jander <david@protonic.nl> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sf: spansion: fixing erasing when sector size >64KiBMarc-André Hébert2010-10-06-4/+3
| | | | | | | | | | | The spansion_erase currently only works when the sector size is 64KB. cmd[1] should contain the higher 8 bit of the 24 bit address of the sector to be erased. Currently it is holding the sector index to be erased which happens to be the same thing when the sector size is 64KB.

* sf: move useful messages from debug to printfMike Frysinger2010-06-30-16/+22
| | | | | | | | | | At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* sf: stmicro: dont send 4 bytes when reading status registerMike Frysinger2009-04-02-3/+3
| | | | | | | | | | | | I can't find anywhere in the datasheet that says the status register needs 3 dummy bytes sent to it before being able to read back the first real result. Tests on a Blackfin board show that after writing the opcode, the status register starts coming back immediately. So only write out the read status register opcode before polling the result.

* sf: set common timeouts in seconds, not millisecondsMike Frysinger2009-04-02-3/+6
| | | | | | | | | | | Since timeouts are only hit when there is a problem in the system, we don't want to prematurely timeout on a functioning setup. Thus having low timeouts (in milliseconds) doesn't gain us anything in the production case, but rather increases likely hood of causing problems where none otherwise exist.

* sf: always read 5 bytes for the idcodeMike Frysinger2009-04-02-11/+5
| | | | | | | | | | | | Some SPI flash drivers like to have extended id information available (like the spansion flash), so rather than making it re-issue the ID cmd to get at the last 2 bytes, have the common code read 5 bytes rather than just 3. This also matches the Linux behavior where it always reads 5 id bytes from all flashes.
