From ed900c55c35a653a0d2ce5489cdeea9a4dd18b5b Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 4 Jun 2012 20:02:24 +0000 Subject: [PATCH] tegra: Rework Tamonten support This commit uses the common Tegra board implementation instead of duplicating a lot of the code. In addition, the Plutux and Medcom specific board files can be removed as the MMC/SD setup is common among all Tamonten-based boards.
