[U-Boot] [PATCH v4 0/5] Implement "fastboot flash" for eMMC

[Steve Rae]

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.

----
While we are struggling with the "sparse_format" copyright and licensing issues,
can we accept the first three patches?
Thanks, Steve

Changes in v4:
- rearranged this patchset so that "sparse_format.h" can be dropped (if we cannot
  resolve the copyright/licensing issues)
- update mmc_get_dev(...) to get_dev("mmc",....)
- update printf() to puts() where applicable
- update debug string as per feedback
- rearranged "sparse format" support in this patchset, in order to isolate...

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
