[yocto] mpc8315e-rdb is probably a poor choice as powerpc example...

Thank you for the reply Bruce.  I suggested the P1010RDB because we have 
one of these (older rev), and we have found few problems working 
periodically with Poky & related master branches over the past couple of 
years.  We also test the mainline kernel on it - typically with success. 
  In other words, it's basically been stable.

It's $545 @ Digikey:

It's a nice system based on e500v2 with 3 GE ports, SATA, USB, FLASH, 
and SD card support ( note - it does have a funky address mux / switch 
on board that limits the use of all peripherals at the same time).

The downside is it's starting to get a little old, so Freescale may 
prefer to point to a T series QorIQ.  I just think it will be important 
to stay away from a DPAA-based device, due to the complexity and my 
perception that some of the related code isn't yet in the public domain 
& may not get there for some time.

And as I stated before, an SMP processor may be a better choice along 
with showing a hypervisor.  It all depends on what's important to Yocto, 
Freescale, and their customers.
