Modified: trunk/package/base-files/files/lib/functions/system.sh trunk/target/linux/ar71xx/base-files/etc/hotplug.d/firmware/10-ath9k-eeprom Log: ar71xx: scan nand ubi partition for ath9k eeprom files The MR18 stores the ath9k eeprom values on the NAND. This patch makes it possible to retrieve the images from there.
