This adds support for partitions of the form "dev.hwpart:part" and "dev#partname". This allows one to flash to eMMC boot partitions without having to use CONFIG_FASTBOOT_MMC_BOOT1_SUPPORT. It also allows one to flash to an entire device without needing CONFIG_FASTBOOT_MMC_USER_NAME. Lastly, one can also flash MMC devices other than CONFIG_FASTBOOT_FLASH_MMC_DEV. Because devices can be specified explicitly, CONFIG_FASTBOOT_FLASH_MMC_DEV is used only when necessary for existing functionality. For those cases, fastboot_mmc_get_dev has been added as a helper function. This allows There should be no conflicts with the existing system, but just in case, I have ordered detection of these names after all existing names. The fastboot_mmc_part test has been updated for these new names. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Simon Glass <sjg@chromium.org>
