mx6sabresd: Add fastboot support
fastboot tool is a convenient way to flash the eMMC, so
add support for it.
Examples of usages:
On the mx6sabresd:
=> fastboot 0
On the Linux PC connected via USB:
$ sudo fastboot getvar bootloader-version -i 0x0525
bootloader-version: U-Boot 2018.01-00550-g7517cfe
finished. total time: 0.000s
$ sudo fastboot reboot -i 0x0525
(this causes the mx6sabresd to reboot)
