Perhaps because some AMD chips are JEDEC compatible?
Quick look to datasheet shows that AM29LV320M is JEDEC
compatible and therefore cfi_flash driver will not work
for it (it works nicely for CFI compatible AMD chips such
as AM29DL323).

There is no generic driver for JEDEC flashes in U-Boot, so
you'll have to provide your own flash driver in board's
directory.
