fastboot: add support for "oem format" command
Add "oem format" command to write partition table. This relies on the env variable partitions to contain the list of partitions as required by the gpt command. Note that this does not erase any data other than the partition table. Signed-off-by: Rob Herring <robh@kernel.org> Reviewed-by: Steve Rae <srae@broadcom.com>
