Yes please.

That shouldn't happen. Where did you put that check? Can you enable 
DEBUG_CFI? What does it print just after you read it from the flash
at line 545:
#ifdef DEBUG_CFI
        printk("Number of erase regions: %d\n", num_erase_regions);
#endif

Having that set to zero is OK for a CFI flash - it means you erase the 
whole device in one go. But that's not the case for your device, or indeed 
any device I've yet encountered, so it's not supported by the code yet.

I'll update my own tree for the board on my desk and check it's still
working for me since the changes to fix 16-bit devices in 8-bit mode were
merged. I have AMD chips in 1x16 arrangement too.
