From a1693a8c2cdc74a5bf33cabaadc2174f2f088dbf Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sun, 16 Jan 2022 18:42:18 +0100 Subject: apm821xx: WNDR4700: utilize ath9k nvmem-cells the WNDR4700 can fetch its calibration data and mac-addresses directly from the "wifi_data" partition. This allows us to get rid of the 10-ath9k-eeprom file for the apm821xx target completely.
