fastboot tool is a convenient way to flash the eMMC, so add support for it. Examples of usages: On the pico-imx7d U-Boot prompt: => fastboot 0 On the Linux PC connected via USB: 1. Retrieving the U-Boot version $ sudo fastboot getvar bootloader-version -i 0x0525 bootloader-version: U-Boot 2018.07-rc1-03888-gde846f9 finished. total time: 0.000s 2. Resetting the board $ sudo fastboot reboot -i 0x0525 (this causes the pico-imx7d to reboot) Signed-off-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
