It is desired to have the led command on the BeagleBoard to allow for some
interaction in the scripts.
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.

I understand the requirement, but I think it is more than time to come
up with a common solution here instead of adding more and more copies
of very similar code.
We already have:
arch/arm/cpu/arm920t/ep93xx/led.c
The file below is mapping the led commands I.E: red_led_on
to at91 I/O calls like at91_set_gpio_value.
A merge, means that a common way of setting GPIO must be available
arch/arm/cpu/arm926ejs/at91/led.c
The only thing the files below do are to initialize the pins for the LED.
While the actual pins are hidden in the configs,
you have a variation of which LEDs are available.
Also you need to enable different clocks.
It is really an extension of the board init file.
Maybe they should be merged with the board file instead.
I personally don't see a problem with keeping the separate file.
There is no commonality between these files and the led.c
in "arch/arm/cpu/arm926ejs/at91/led.c"
board/atmel/at91cap9adk/led.c
board/atmel/at91rm9200dk/led.c
board/atmel/at91rm9200ek/led.c
board/atmel/at91sam9260ek/led.c

board/eukrea/cpu9260/led.c
board/logicpd/zoom2/led.c
board/ns9750dev/led.c
board/psyent/pk1c20/led.c
Please, let's unify these.
Best regards,
Wolfgang Denk
The proposed patch is adding a command, and
which uses the coloured LED interface and there
is no commonality between this code and
the code in the board and cpu directories.
