The benefit I see is that it logically groups all QorIQ parts together, 
which I believe is important.

When Freescale needs to provide support for LS2A (next generation) DPAA, 
the current organization will become a mess.  A lot (if not most) of the 
QorIQ BSP layer is for DPAA / networking, and I don't think it will make 
sense to have these duplicated in both meta-fsl-ppc and meta-fsl-arm, or 
have DPAA code that will be built for the ARM in meta-fsl-ppc (or vice 
versa).

I would hope that having this code organized in logical layers under the 
scope of QorIQ would make it more manageable in migrating from something 
like a TXXX device to an LS2A device.

However, I certainly understand you not wanting to change everything 
before there is stability in what we currently have.

I'm building with meta-fsl-ppc on a daily basis, but I'm not using 
anything else in the community tree (e.g., demos, meta-fsl-arm, repo, 
etc.) because my perception is it isn't ready for me as a QorIQ developer.

Zhenhua, when are you looking to make these changes?  Will this be a 
master-next sort of thing after the end of the year, or do you want to 
do all this now?
