[Buildroot] Using the new Ti-gfx with Qt5

I see you are on 3.10 kernel, the SDK has been tested so far with 3.8 and might need minor patches for looking at the right header files with later kernels.

regards,
Prabu

Dear Thomas:

Thank you for your kind words as usual as I try to understand the new additions to buildroot.

I did find in "hardware handling" an enable for ti-gfx and enabled it along with the kernel and was able to get all the way to the compilation of the ti-gfx stuff until it errored in compilation.

So, at this point, I cannot quite tell if this is a mis-configuration or a missing patch in the ti-gfx stuff.

I did get this all working 2 months ago with some hand tweaking before Spenser added his patches and am circling back to test the new stuff to see if I can move to it.

I am including the .config file currently being used with the
buildroot-20130731 test for reference. I totally understand you are very busy keeping all the rest of this together so I will keep studying in the background and look forward to any advice you can offer.

Charles
