This patch bases on patch of Ulf Samuelsson ([PATCH 1/1] ARM: Add command to control coloured led from the console, Wed Jan 7 21:09:55 CET 2009) It allows any board implementing the user LED API to control the LEDs from the console.
led [ 1 | 2 | 3 | 4 | 5 | all ] [ on | off ]
Adding configuration item CONFIG_CMD_LED enables the command. The items CONFIG_LED1...5 configure the associated gpio-pins.
