From 1fc5c28bc260c72b4f9cefdf55bfd10504916457 Mon Sep 17 00:00:00 2001
From: Jason Kridner <jkridner@beagleboard.org>
Date: Thu, 20 May 2010 05:41:26 -0500
Subject: [PATCH 43/50] Add 'led' command
This patch allows any board implementing the coloured LED API
to control the LEDs from the console.
led [green | yellow | red | all ] [ on | off ]
or
led [ 1 | 2 | 3 | all ] [ on | off ]
Adds configuration item CONFIG_CMD_LED enabling the command.
Partially based on patch from Ulf Samuelsson:
http://www.mail-archive.com/u-boot@lists.denx.de/msg09593.html.
(cherry picked from commit aaf47f8d6af81393b7d3275d69b5dbdf07a3d6fb)
(cherry picked from commit 3d314bf59a48c2ee93d06d50b81f109af6a6c1ec)
