Just of the records. I you agree with following commit message I will
resend the patch.
------------------------------------------------------
Exynos boards support GPIO and PWM based LEDs

Odroid boards support led activity to indicate the various status
Red led - power: hooked up to 5V power
Blue led - alive Solid light : u-boot is running
flashing : Kernel is running (heart beat)
-------------------------------------------------------
If you want to add some thing more please suggest me.

Earlier I was just frustrated.
