Did you solve this already? I needed a super early driver that was called in ar71xx land before the flash addressing was remapped into a normal NOR flash device. It extracted out the calibration images and exposed them as firmware blobs that can be then accessed via named firmware_get() calls. So now all (i think!) of the ar71xx chips and the ath driver can now access their calibration data /after/ the system has booted, allowing me to use ath modules. -adrian
