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
