This is a known bug in Kodi, which nobody has investigated so far.

I would prefer this to be:

	select BR2_PACKAGE_IMX_GPU_VIV_G2D if BR2_PACKAGE_IMX_GPU_VIV

Change this to:

ifeq ($(BR2_PACKAGE_IMX_GPU_VIV)$(BR2_PACKAGE_LIBFSLVPUWRAP),y)

You're talking about imx-lib here, but it doesn't appear anywhere, so
this comment is confusing, and can be removed IMO.

Remove linux from this line. libfslvpuwrap already depends on it, so
it's not really useful to have it.

Maybe above this line:

# Kodi needs access to some specific kernel headers, which are
# Freescale specific and therefore not part of the toolchain, so we have
# to access directly the headers from the kernel sources

I think this way your patch would be a bit easier to understand.
Basically the logic is that as soon as libfslvpuwrap *and*  the
imx-gpu-viv packages are enabled, i.MX6 support in Kodi will be enabled.

Could you rework this, test that it works fine for you, and resubmit?

Thanks a lot!
