[U-Boot] [PATCH] at91: Add esd gmbh MEESC board support
Daniel Gorsulowski
Daniel.Gorsulowski at esd.eu
Tue Jun 23 12:21:09 CEST 2009
This patch adds support for esd gmbh MEESC board.
The MEESC is based on an Atmel AT91SAM9263 SoC.
Signed-off-by: Daniel Gorsulowski <Daniel.Gorsulowski at esd.eu>
---
Jean-Christophe: This patch requires an up-to-date mach-types.h,
please sync it.
