> E1120 motherboard

> E1116 PMU board
>
> The motherboard configuration switches are set as follows:
> SW1=0 SW2=0 SW3=5

> Other combinations of daugher boards may work to varying degrees, but will

Builds OK for me when applied to u-boot-tegra/master. I don't have a Whistler
here to test with, though.
I'll add this series to the next pull request.
