Now with kernel moving to all device tree, the default boot command is changed to pass the device tree blob. Also, adding the findfdt command to get the dt-blob based on the board.
Thanks to Tom Rini trini@ti.com for suggesting this.
Signed-off-by: Sricharan R r.sricharan@ti.com --- [V4] Added environment variables bootdir, bootpart and added loadimage, loadfdt commands as per Tom's suggestion.
