U-Boot

/u-boot.imx

U-Boot binary blob. This will be written to the SPI flash. The imx_type variable of the new file and the existing U-Boot installation on SPI flash will be checked to ensure the file being written is compatible with the current CPU. If the file /u-boot.imx.md5 is present on the USB drive, this will be used to verify the data written to SPI flash.
