+	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.

+	---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.
