dm: spi: Move slave details to child platdata

2015-01-30T00:09:56Z

At present we go through various contortions to store the SPI slave's chip select in its private data. This only exists when the slave is active so must be set up when it is probed. Until the device is probed we don't actually know what chip select it will appear on. However, now that we can support per-child platform data, we can use that instead. This allows us to set up the chip select when the child is bound, and avoid the messy contortions. Unfortunately this is a fairly large change and it seems to be difficult to break it down further.

sf: Enable byte program support

2014-12-13T22:08:04Z

Enabled byte program support for sst flashes in sf. Few controllers will only support BP, so this patch gives a tx transfer flag to set the BP so-that sf will operate on byte program transfer. A new TX operation mode SPI_OPM_TX_BP is introduced for such SPI controller to use byte program op for SST flash. Signed-off-by: Jagannadha Sutradharudu Teki Tested-by: Bin Meng

spi: sf: Support byte program for sst spi flash

2014-12-13T22:08:04Z

Currently if SST flash advertises SST_WP flag in the params table the word program command (ADh) with auto address increment will be used for the flash write op. However some SPI controllers do not support the word program command (like the Intel ICH 7), the byte programm command (02h) has to be used.

spi: Fix flag collision for SST_WP

2014-12-13T22:08:04Z

At present SECT_4K is the same as SST_WP so we cannot tell these apart. Fix this so that the table in sf_params.c can be used correctly. Reported-by: Jens Rottmann Signed-off-by: Simon Glass Reviewed-by: Jagannadha Sutradharudu Teki
