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?
