8-bit AMD/Spansion flashes are supported by current driver. The patch would, in fact, break support for many such flashes (29F016D, for example). Only in a special case of 16-bit flash configured to work in 8-bit mode (29DL640D in 8-bot mode, for example), such a change in command address can be needed but IMHO this should be handled in run-time according to CFI info.

Ummm, such a change is needed at least by S29GLxxxM flashes, but I didn't know anything about 29F016D. Sorry about that. Any suggestion as info from to CFI which would select the correct command addresses?
