ccimx6ulstarter: add U-Boot scripts for deploying and booting the system
- boot.txt Sets the device tree filename basing on the SOM variant read from the HWID and boots from NAND. - install_linux_fw_sd Deploys a full system (as generated by Digi Embedded Yocto) from a FAT formatted micro SD card into the NAND flash. The u-boot-dey recipe is now fully shared by ccimx6 and ccimx6ul platforms so we can remove the platform-specific appends. Signed-off-by: Hector Palacios <hector.palacios@digi.com>
