* sf: Use spi_flash_alloc() in each SPI flash driverSimon Glass2013-03-19-7/+1
| | | | | | | | Rather than each device having its own way to allocate a SPI flash structure, use the new allocation function everywhere. This will make it easier to extend the interface without breaking devices. Signed-off-by: Simon Glass <sjg@chromium.org>
* spiflash: at25: using common spi flash operationBo Shen2012-09-17-3/+8
| | | | | | | | Using common spi flash operation function to replace private operation funtion Signed-off-by: Bo Shen <voice.shen@atmel.com> Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

* sf: localize erase funcsMike Frysinger2011-04-12-2/+2
| | | | | | | 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: add struct spi_flash.sector_size parameterRichard Retanubun2011-04-12-4/+1
| | | | | | | | | | | | | | | 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 read functionsMike Frysinger2011-04-11-16/+2

* sf: unify status polling for ready bitMike Frysinger2011-04-11-29/+2
| | | | | | | | 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: move useful messages from debug to printfMike Frysinger2010-06-30-3/+4
| | | | | | | | | | 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: add GPL-2 license infoMike Frysinger2009-10-24-0/+1
| | | | | | | Some of the new spi flash files were missing explicit license lines. Signed-off-by: Mike Frysinger <vapier@gentoo.org> CC: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>

* spi flash: fix crash due to spi flash miscommunicationBrad Bozarth2009-01-24-1/+2
| | | | | | | | | | | Higher spi flash layers expect to be given back a pointer that was malloced so that it can free the result, but the lower layers return a pointer that is in the middle of the malloced memory. Reorder the members of the lower spi structures so that things work out.

* SPI Flash subsystemHaavard Skinnemoen2008-06-03-0/+362
This adds a new SPI flash subsystem. Currently, only AT45 DataFlash in non-power-of-two mode is supported, but some preliminary support for other flash types is in place as well. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
