* another bootloader.
* Also use that same offset (0x90000) to load the rescue image later on (by
* adding it onto the flash address where U-Boot is supposed to be stored by
* the legacy loader, 0x440000, resulting in offset 0x4d0000 on the flash).
* When coming up with a valid environment in ubi, first try to load the
* kernel from a ubi volume kernel, if that fails, fallback to the rescue
* image stored in boot partition. As a last resort try booting via
* DHCP/TFTP.
* In case there is no valid environment, first probe for a uimage in ram left
* behind by the first bootloader on a tftp boot.
* If that fails, switch to normal boot order and save environment.
* The loader is supposed to be written to flash at offset 0x440000 and loaded to
* RAM at 0x64000000
