As most of you know, the mpc8315e-rdb is the powerpc reference platform
in meta-yocto-bsp. This is old technology and not a good representative
of QorIQ.
I suggest something from the P or T family be used. The P1010RDB is
probably a good choice, but others may prefer an SMP machine.
I'm willing to help to make it happen.

We've been working with FSL to find a suitable replacement for some time, and
the discussions were happening in the sprint, but stalled for the summer months.

The choice is equally about the machine and about the ability to purchase the
target at a reasonable price. We don't use hard to find, or expensive boards.
So if you do have specific suggestions, and purchase information, send it along
and it can be rolled into the ongoing discussions.

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:
http://www.digikey.com/product-search/en?x=0&y=0&lang=en&site=us&keywords=P1010RDB
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.

ouch. personally, i think that's too pricey for one of the yocto
reference boards. it should be affordable by *hobbyists*, which
suggests a price of at most $200, if not less. $545 is simply too
expensive.

Agreed!
However, the currently used mpc8315e-rdb is $515 at Digikey:
http://www.digikey.com/product-detail/en/MPC8315E-RDBA/MPC8315E-RDBA-ND/2186258
Basically same price

ouch again. i didn't know that as i don't have much interest in PPC
boards. i'm still convinced that every yocto reference board should be
"affordable". it need not be fully-featured, it need only represent a
proof of concept in the sense of building a simple, bootable image.
are there no decent PPC dev kits in that price range? none?
