If my memory doesn't fail me, the NAND controller is called NFC v1 on
pxa3xx, and NFC v2 on mvebu SoCs.

I'm wondering if we can pick a better name for this driver in barebox.
Maybe something like 'mv_nfc_nand' ?

Also, I think you can get rid of the 'builtin_flash_types' struct and
all the device detection routines, which are really duplicating the
MTD's lower level job.

I never removed it from the Linux driver, because I was afraid of
regressions and there are little testers around. However, on Barebox we
can benefit from removing that, and starting with a cleaner driver.

Just my two cents,
