From 689be5f83c17af6221764ab3a3890510af3c9022 Mon Sep 17 00:00:00 2001 From: Igor Grinberg Date: Mon, 16 Sep 2013 21:49:58 +0300 Subject: [PATCH] cm-t35: move the eeprom code to common place Compulab boards use the same eeprom code, so move the eeprom related code to live under board/compulab/common directory. Also make several adjustments to eeprom functions namespace, so it will be generic for compulab boards.
