Hi,

Are all the kernel options mentioned here in the linux-yocto-3.8 repo?
i.e. if I wanted to build a BSP using these config fragments, would I be
able to, or did I miss those patches?

Normally, when submitting a new BSP, you should also submit the kernel
patches that go with it as well as the oe metadata e.g. the meta-intel
layer, so that people can build and test it out.

>From a quick glance at this, though, I see that EMGD is essentially
hard-coded into the BSP (as well as i915 too) - did you look at the
current BSPs in meta-intel that add EMGD conditionally as a kernel
feature?  I think that someone should be able to build a baytrail BSP
without having to use EMGD.
