This patch extends the U-Boot "led" command to support automatic blinking by setting a blink frequency in milliseconds. Additionally the number of supported LEDs is increased to 6 (0...5). This will be used by the PCA9551 LED driver. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Tom Rini <trini@konsulko.com>
