This is used on all other Panda revisions.

Why are we just disabling this for all devices when one device is the issue?
And as discussed off line I have an older B3 which boots fine on the uBoot mainline.

So what is the difference between your B3 and my B3?  Please answer this to the community or
point to a reference were one can determine what B3 board they have
