# The boot ROM in the SoC will start loading code if a special BOOT0 header is
# found (at an offset of 8KiB in either NAND or SD), and the checksum is
# correct. This header is normally added by the 'mxsunxiboot' tool. The boot ROM
# will load at most 24KiB of data to SRAM, so limit the file size accordingly.
# The BOOT0 header takes 32 bytes, so limit our file to 24KiB - 32 bytes.
# FIXME: Figure out how to safely integrate in coreboot.rom.
# FIXME: The file passed to mksunxiboot should only include the bootblock due
# to size limitations.
