# Wolfgang saw data corruptions in stage2 when dealing with ECC data on random writes
# to NAND. Disabling the unit-at-a-time optimization reproducibly fixed the bug.
# The compiler may be optimizing in a way that conflicts with how the hardware ECC
# registers work. Since other register accesses might be affected too it seems the best
# is to disable this optimization right now.
