Comment (by Joel Sherrill):

 The patch touches code used by motorola_shared and beatnik. The patch has
 only been tested on qemu. We need it tested on hardware.

Comment (by Sebastian Huber):

 We have two Qemu PowerPC BSPs qemuprep and qemuppc. I touched qemuppc.
 This ticket is for qemuprep?

Comment (by Joel Sherrill):

 I wanted to note two things:

 * Chris is supposed to be given access to real hardware to test this on.

 * Sebastian committed a change to switch qemuppc to use the shared linker
 script. This might impact your patch. Please update the patch if needed
 per the master.
