[U-Boot] [PATCH] Initial support for Orion5x SoC and EDMini board
Albert Aribaud
albert.aribaud at free.fr
Sat Nov 14 02:01:55 CET 2009
This patch adds initial u-boot support for the Marvell orion5x
SoC and the LAcie ED Mini V2 board--support is limited to serial,
flash and environment. Further support will be added as devices
common with kirkwood are made useable across SoCs.
