I think the CFI driver needs some basic rework to get ridof such pointer accesses and use proper accessor functions/macros instead to make sure we have all the memory barriers etc. we may need.
I happen to have a patch lying around which does exactly that, in addition to a few other cleanups.
Stefan, if you could push out all the stuff you have pending to the CFI custodian tree, I can rebase my stuff on top of that and submit for review.
It looks like it just uses DQ6/toggle if I'm reading the code correctly.
Note that Linux calls a (map)->write() function to access the flash.
Only if CONFIG_MTD_COMPLEX_MAPPINGS=y. Otherwise, it uses __raw_write[bwl].
