To determine whether we have been booted from an eMMC boot partition, we

load the SPL. This involves a checksum check, which currently relies on
the SPL being wrapped in an "eGON" header.
If a board has secure boot enabled, the BROM will only accept the "TOC0"
format, which is internally very different, but uses the same
checksumming algorithm. Actually the only difference for calculating the
checksum is that the size of the SPL is stored at a different offset.
Do a header check to determine whether we deal with an eGON or TOC0

unchanged.
