Sheep board is designed by Rockchip as a EVB for rk3368. Currently it is able to boot a linux kernel and system to console with the miniloader run as fist level loader.
Reviewed-by: Simon Glass sjg@chromium.org Signed-off-by: Andy Yan andy.yan@rock-chips.com ---
Changes in v2: - add a README to describe how to boot the board
