[U-Boot] [PATCH v3 0/4] Implement "fastboot flash" for eMMC

[Steve Rae <srae@broadcom.com>]

This series implements the "fastboot flash" command for eMMC devices.
It supports both raw and sparse images.

NOTES:
- the support for the "fastboot flash" command is enabled with CONFIG_FASTBOOT_FLASH
- the support for eMMC is enabled with CONFIG_FASTBOOT_FLASH_MMC_DEV
- (future) the support for NAND would be enabled with CONFIG_FASTBOOT_FLASH_NAND(???)

This has been tested on ARMv7.

Changes in v3:
- remove most references to 'mmc',
  which leaves only one mmc specific function: mmc_get_dev()

Changes in v2:
- split large function into three
- improved handling of response messages
- additional partition size checking when writing sparse image
- update README.android-fastboot file
- new in v2
