[Buildroot] AM3517 Neon, OpenGL & EGLFS support

[Charles Krinke]

Dear Wojceich:

Your new patch looks like the only difference is the line changing
package/opengl/libgles/libgles.mk from

-ifeq ($(LIBGLES_DEPENDENCIES),)
+ifeq ($(LIBGLES_DEPENDENCIES),y)

I still get the same error when compiling Qt and that is:

patching file mkspecs/common/posix/qplatformdefs.h
>>> libgles undefined Configuring
>>> libgles undefined Building
>>> libgles undefined Installing to target
>>> libegl undefined Extracting
>>> libegl undefined Patching package/opengl//libegl
>>> libegl undefined Configuring
echo "No libEGL implementation selected. Configuration error."

So, from this, I am assuming there is some mis-configuration on my end
that is causing buildroot to go into the package/opengl/libgles
directory when perhaps it should be going to either somewhere in Qt
(QtOpenGl perhaps) or somewhere in Graphics_SDK_XXX. I am searching
more into that.

Perhaps one way to converge this would be to get your patch committed
to the buildroot repository. The only parts that appear to be missing
are the QMAKE_LIBS_INCDIR_OPENGL* ^ BR2_PACKAGE_QT_OMAP_LIB_PATH from
night before last build on the buildroot server.

If we could get the logic that pertains to the external TI
Graphics_SDK committed into buildroot then those folks that wish to
use QtDeclarative or another option that needs the Graphics_SDK, then
we could be a bit further along for all.

Charles
