This is a series of cleanups to the CFI driver I did while debugging why it refused to work on my AVR32 boards, rebased on top of the latest CFI custodian tree with "[PATCH] CFI: synchronize command offsets with Linux CFI driver" applied as well.
I'm not completely done yet, as I need more fixes to make the CFI driver work on boards like the ATNGW100. But these initial patches are seriously painful to rebase (especially #3 in this series,) so I'd like some feedback from others if I'm moving in an acceptable direction with this.
I've compile-tested the whole thing using MAKEALL on ppc (no point in testing on avr32 since no boards use this driver yet.) mcc200 failed, but it complains about lots of undefined symbols that has nothing to do with the CFI driver, so I'm pretty sure it isn't my fault.
Please let me know which parts of this are acceptable, and if there's something that can be done in a better way. And if you merge parts 1-3 (or even more of them), I'd be _very_ happy :-)
There are a couple of remaining cleanups I'd like to make that go on top of this stuff, mostly related to refactoring the command set handling and adding manufacturer-specific fixups.
