Are you saying that it shouldn't be switchable through a command line
option (but rather based on information in the partition table or
something similar), or are you saying that we shouldn't need different
ECC modes for different parts of the flash (boot ROM vs. software
implementations, whether block 0 has different ECC requirement etc)?
