We have a bunch of the Freescale boards that have a 3.x kernel support. It
is also integrated into the mainline.

Freescale bsp page is


We are currently using this for a utm box and the kernel is pretty stable.
We use the p2040 processor variant. unfortunately it is only 32 bit.

Let me know know what I need to do next and I can try to get a build going.

I have  also asked IBM for a power loaner box but that may take a couple
of months to arrive.
