From 9dbeb91a8b97e2892c04461e28d2bdd0198b719d Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 14 Jan 2009 20:17:08 +0100 Subject: ath9k: get EEPROM contents from platform data on AHB bus On the AR913x SOCs we have to provide EEPROM contents via platform_data, because accessing the flash via MMIO is not safe. Additionally different boards may store the radio calibration data at different locations.
