For CFI chips, I believe it works. The Compaq iPAQ 31xx series have
precisely this arrangement.
I'm interested to know whether it's the CFI probe or the JEDEC probe which
is working on your device. Please could you make it print the contents of
cfi->cfi_mode after detecting the chip?
cfi->mode = 1 which means that MTD detects in JEDEC mode. This result is
obtained by compiling the kernel with 1x16 geometry specification, and the
modification to cfi_qry_mode I talked about in a previous mail.
But Atmel chips are CFI, right? Correct me if I am wrong.
