I'm working with an Atmel AT49BV162A and noticed that the CFI code doesn't properly detection the erase regions for the device.

Its a Bottom boot device and atmel (at least on this device) does swap the erase region information.

I was wondering what the 'proper' way was to add some sort of fixup for this device so its regions are detected correctly.

Hi Kumar,

We do geometry reversal for AMD/Spansion style flash devices. Look for "geometry_reversed" in the code.

The variable is set from CFI table but CFI 1.0 tables do not have the appropriate information. :(

So, the geometry reversal decision is made as a guess from device id (which could be wrong in which case you need to override the geometry_reversed flag based on exact match of manufacturer_id and device_id.

Let me know how it goes.
