I'm not familiar with the AT26 series, but when I was writing the M25Pxx
driver I did notice that the M25 and AT25 parts shared the same
underlying protocol. However, I didn't add any AT25 parts to the
supported component list since I didn't have any to test the driver
against. If the AT26 shares the same protocol as the AT25/M25P parts,
you may be able to use the existing M25Pxx driver by just adding a
suitable device definition.
Chris.
