No problem. I have been slow on reacting.

If you had to make some changes to this patch, then please send the
changes / updated patch version as a new version (v3) to the list. So
that it applies clean now. And please change the commit text accordingly.

Only that? IIRC, then without this patch, writing to the 8-bit flash
didn't work at all. But I don't have such a board, so I can't really
test myself.

Please send this additional change/fix as a separate patch to the list
as well.
