+ Prepend a 1536 byte (empty) header to the U-Boot image file, to be
+ filled with magic values post build. The Allwinner provided boot0
+ blob relies on this information to load and execute U-Boot.
+ Only needed on 64-bit Allwinner boards so far when using boot0.

+ ---help---
+ Insert some ARM32 code at the very beginning of the U-Boot binary
+ which uses an RMR register write to bring the core into AArch64 mode.
+ The very first instruction acts as a switch, since it's carefully
+ chosen to be a NOP in one mode and a branch in the other, so the
+ code would only be executed if not already in AArch64.
+ This allows both the SPL and the U-Boot proper to be entered in
+ either mode and switch to AArch64 if needed.
