[Simon Glass]

This has been replaced with a new LED framework, so drop this old code
and documentation.

-Status LED
-========================================
-
-This README describes the status LED API.
-
-The API is defined by the include file include/status_led.h
-
-The first step is to enable CONFIG_LED_STATUS in menuconfig:
-> Device Drivers > LED Support.
-
-If the LED support is only for specific board, enable
-CONFIG_LED_STATUS_BOARD_SPECIFIC in the menuconfig.
-
-Status LEDS 0 to 5 are enabled by the following configurations at menuconfig:
-CONFIG_STATUS_LED0, CONFIG_STATUS_LED1, ... CONFIG_STATUS_LED5
-
-The following should be configured for each of the enabled LEDs:
-CONFIG_STATUS_LED_BIT<n>
-CONFIG_STATUS_LED_STATE<n>
-CONFIG_STATUS_LED_FREQ<n>
-Where <n> is an integer 1 through 5 (empty for 0).
-
-CONFIG_STATUS_LED_BIT is passed into the __led_* functions to identify which LED
-is being acted on. As such, the value choose must be unique with with respect to
-the other CONFIG_STATUS_LED_BIT's. Mapping the value to a physical LED is the
-reponsiblity of the __led_* function.
-
-CONFIG_STATUS_LED_STATE is the initial state of the LED. It should be set to one
-of these values: CONFIG_LED_STATUS_OFF or CONFIG_LED_STATUS_ON.
-
-CONFIG_STATUS_LED_FREQ determines the LED blink frequency.
-Values range from 2 to 10.
-
-Some other LED macros
----------------------
-
-CONFIG_STATUS_LED_BOOT is the LED to light when the board is booting.
-This must be a valid LED number (0-5).
-
-CONFIG_STATUS_LED_RED is the red LED. It is used to signal errors. This must be
-a valid LED number (0-5). Other similar color LED's macros are
-CONFIG_STATUS_LED_GREEN, CONFIG_STATUS_LED_YELLOW and CONFIG_STATUS_LED_BLUE.
-
-General LED functions
----------------------
-The following functions should be defined:
-
-__led_init is called once to initialize the LED to CONFIG_STATUS_LED_STATE.
-One time start up code should be placed here.
-
-__led_set is called to change the state of the LED.
-
-__led_toggle is called to toggle the current state of the LED.
-
-Colour LED
-========================================
-
-Colour LED's are at present only used by ARM.
-
-The functions names explain their purpose.
-
-coloured_LED_init
-red_LED_on
-red_LED_off
-green_LED_on
-green_LED_off
-yellow_LED_on
-yellow_LED_off
-blue_LED_on
-blue_LED_off
-
-These are weakly defined in arch/arm/lib/board.c to noops. Where applicable, define
-these functions in the board specific source.
-
-TBD : Describe older board dependent macros similar to what is done for
-
-TBD : Describe general support via asm/status_led.h
