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)?
