ARM: UniPhier: add environment variable to update images in NAND
To boot UniPhier boards with the NAND boot mode, two images (u-boot-spl.bin and u-boot-dtb.img) must be written at the correct offset addresses. TFTP downloading is useful to update such images in the NAND device. We generally do: => nand erase 0 0x100000 => tftpboot u-boot-spl.bin => nand write $loadaddr 0 0x10000 => tftpboot u-boot-dtb.img => nand write $loadaddr 0x10000 0xf0000 It is a tedious and error-prone operation. This commit provides the shorthand: => run nandupdate Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
