[coreboot-gerrit] Change in coreboot[4.8_branch]: cpu/allwinner: Prepend the BOOT0 header to the bootblock.bin

[Arthur Heymans (Code Review)]

Hello build bot (Jenkins), Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/35401

to look at the new patch set (#2).

Change subject: cpu/allwinner: Prepend the BOOT0 header to the bootblock.bin

cpu/allwinner: Prepend the BOOT0 header to the bootblock.bin

Instead of prepending the BOOT0 header to the full coreboot.rom to
create a new file called BOOT0, prepend to the bootblock.bin that gets
included in BOOTBLOCK FMAP region.

This updates mksunxiboot to reflect that it only operates on the raw
bootblock.bin and not the final image which as some padding in the
BOOTBLOCK FMAP region:
- given the necessary alignment on some boot media assume that the
  remainder bytes after the bootblock will be filled with 1's
- don't allow bootblocks larger than 24K as the BROM won't load these
  fully anyway.
