2015-04-18dm: sf: Add driver model read/write/erase methodsSimon Glass
Permit use of a udevice to talk to SPI flash. Ultimately we would like to retire the use of 'struct spi_flash' for this purpose, so create the new API for those who want to move to it. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-22dm: sf: Add a uclass for SPI flashSimon Glass
Add a driver model uclass for SPI flash which supports the common operations (read, write, erase). Since we must keep support for the non-dm interface, some modification of the spi_flash header is required. CONFIG_DM_SPI_FLASH is used to enable driver model for SPI flash.

2014-10-22sf: Tidy up public and private header filesSimon Glass
Since spi_flash.h is supposed to be the public API for SPI flash, move private things to sf_internal.h. Also tidy up a few comment nits. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
2014-09-24spl: replace CONFIG_SPL_SPI_* with CONFIG_SF_DEFAULT_*Nikita Kiryanov
Currently, CONFIG_SPL_SPI_* #defines are used for controlling SPI boot in SPL. These #defines do not allow the user to select SPI mode for the SPI flash (there's no CONFIG_SPL_SPI_MODE, so the SPI mode is hardcoded in spi_spl_load.c), and duplicate information already provided by CONFIG_SF_DEFAULT_* #defines. Kill CONFIG_SPL_SPI_*, and use CONFIG_SF_DEFAULT_* instead.

2013-03-19sf: Add spi_flash_alloc() to create a new SPI flash structSimon Glass
At present it is difficult to extend the SPI flash structure since all devices allocate it themselves, and few of them zero all fields. Add a new function spi_flash_alloc() which can be used by SPI devices to perform this allocation, and thus ensure that all devices can better cope with SPI structure changes.

2011-04-12sf: add struct spi_flash.sector_size parameterRichard Retanubun
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).
