From: Stephen Warren swarren@nvidia.com

Whistler is a highly configurable Tegra evaluation and development board. This change adds support for the following specific configuration:

E1120 motherboard E1108 CPU board E1116 PMU board

The motherboard configuration switches are set as follows: SW1=0 SW2=0 SW3=5 S1/S2/S3/S4 all on, except S3 7/8 are off.

Other combinations of daugher boards may work to varying degrees, but will likely require some SW adjustment.

(In at least some configurations) Whistler uses UART1 on pingroups UAA, UAB.

We really shouldn't be using configs to deal with this. It should be a run-time check.

I recall you saying that we could use the ODM bits for this?
