This chip is supported by the CFI driver (the ATNGW100 board relies on
that.)

This chip is not yet supported by the CFI driver. It needs a fixup due
to reversed erase region information, but since the CFI driver only
reads the low 8 bits of the ID, there's currently no way to tell it
apart from AT49BV642D, which doesn't need this fixup.

If someone can figure out how to read a 16-bit ID when appropriate, I
suspect we can get rid of quite a few board-specific flash drivers
(including the one for ATSTK1000).

Unfortunately, I don't have the time to look into this myself at the
moment.
