It would probably be more appropriate to place it after the first Atmel
fixup in the cfi_fixup_table, yes.

Really unsure why I ended up putting it in the fixup_table, because I
used the fixup_unlock_powerup_lock as reference.

It is probably more correct that I set the FeatureSupport 0x20 (32)
feature to indicate that the flash has "Instant block lock". I'll
submit a v2 for the latter unless you have some other feedback?
