This is to encode MCU flashes that have ECC, where it is common that only a complete clear of the word is allowed. This is a more restrictive version of `MultiwriteNorFlash` as it cannot encode flashes with ECC support.

While obvious to add the trait like this, I'm not sure this is the best way to do it... In Sequential-Storage I'd like to be able to switch behaviour depending on whether a true multiwrite can be done, or only a clear to 0. I'm not sure on how to do this. However, say we change the MultiWriteNorFlash trait to have an associated const bool that declares the ability, then we could make a meaningful selection so it can use the pessimistic algo for clear-only. |
