Revert "sf: Fix quad bit set for micron devices"

2016-12-15T17:33:16Z

This reverts commit c56ae7519f141523ba1248b22b5b5169b21772fe. Once the 'Quad Enable' bit is cleared in their Enhanced Volatile Configuration Register (EVCR), Micron memories expect ALL commands to use the SPI 4-4-4 protocol. Commands using SPI 1-y-z protocols are no longer accepted. Within the reverted commit, the write_evcr() function is implemented using the spi_flash_write_common(), which is a shortcut for the [ spi_flash_cmd_write_enable(), spi_flash_cmd_write(), spi_flash_cmd_wait_ready() ] sequence. Since the internal state of the Micron memory has been changed when the spi_flash_cmd_write() function completes, the later call of the spi_flash_cmd_wait_ready() function fails. Indeed the SPI controller driver is not aware of the SPI protocol switch. Further patches will fix the support of Micron QSPI memories.

sf: Do not force the DT memory map size to exactly match the device

2016-12-15T15:57:28Z

As long as the memory mapped size specifeid in the DT is the same or bigger than the device size, it will work. So do not force the sizes to be identical. Signed-off-by: Phil Edworthy Reviewed-by: Jagan Teki

mtd: spi: don't return -1 when scan succeed

2016-12-15T15:57:28Z

In spi_flash_scan, 'ret' is initialled to -1, but 'ret' is not always used to store a return value, in that case, even when the function succeed, an error (-1) will be returned. Lets just return 0 if we hit the end of the function. Signed-off-by: Fabien Parent Reviewed-by: Jagan Teki

spl: Add a name to the SPL load-image methods

2016-12-09T13:40:13Z

It is useful to name each method so that we can print out this name when using the method. Currently this happens using a separate function. In preparation for unifying this, add a name to each method. The name is only available if we have libcommon support (i.e can use printf()). Signed-off-by: Simon Glass

spi: Add of-platdata support to SPI and SPI flash

2016-11-26T00:59:30Z

Some boards may want to use these subsystems with of-platdata in SPL. Add support for this by avoiding any device tree access in this case. Signed-off-by: Simon Glass
