This is a resend of the whole series rebased onto the latest head of the CFI tree.
Patch #3 is not actually present since it's too large to fit under the 40K limit. I've put it on a web server instead:
http://avr32linux.org/twiki/pub/Sandbox/UbootCfiCleanup/0003-cfi_flash-Reord...
I did a quick test on one of my avr32 boards and while it identified the flash just fine, it couldn't erase it. I think the flash chip needs to be unprotected, and the current code doesn't do this (it's kind of a quirk with the particular Atmel chip I'm using, AT49BV6416.) I'm planning to rework the code dealing with chip-specific quirks later on and add code to smack this chip on the head as needed. It also has a geometry reversal issue which is not detected properly by the current code (I think there's a reason this chip was quickly replaced by AT49BV642D, which doesn't have any of these problems.)
