Fastboot currently supports MMC and NAND flash devices. Similarly, extend the support to SPI flash memories. Note that in this initial implementation, partitions on the device are not supported yet, but raw partitions can be set in U-Boot environment. To define a raw partition descriptor, add an environment variable similar to the MMC case: ``` fastboot_raw_partition_<raw partition name>=<offset> <size> ``` for example: ``` fastboot_raw_partition_boot=0x0 0x1000000 ``` Signed-off-by: Ariel D'Alessandro <ariel.dalessandro@collabora.com> Reviewed-by: Mattijs Korpershoek <mkorpershoek@kernel.org>
