From: Pali Rohár <p...@kernel.org>
The SPL code now already parses kwbimage v1 headers where all necessary
information about how to load and execute main U-Boot is present. The
legacy 64-byte U-Boot header is not used anymore.
Remove this 64-byte header by putting u-boot.bin binary (instead of
u-boot.img) into kwbimage v1 and let SPL code or BootROM to load U-Boot
directly at its execution address.
