Ok, it compiles ;) In case anything works with this [1], it adds about
6 different paths depending on protocol versions and what the chip sup-
ports; would be nice to have most of them tested. For instance testing
the S25FL256S patches one by one as they add different ways how to
handle the higher addresses. Also, in case you can downgrade Dediprog
firmwares, a test with something <5.5.0 would be good as well.
