[U-Boot] [PATCH v3 1/7] tegra: Rework Tamonten support
Thierry Reding
thierry.reding at avionic-design.de
Tue Jun 5 08:02:24 CEST 2012
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.
