# ALARM: Kevin Mihelich <kevin@archlinuxarm.org>
#  - Removed DRI and Gallium3D drivers/packages for chipsets that don't exist in our ARM devices (intel, radeon, VMware svga).
#  - Build v7h with -O1 instead of -O2
#  - Removed libgles, libegl and khrplatform-devel from conflicts for marvell-libgfx compatibility.
#  - Moved .pc files to mesa-libgl that referencing libraries in mesa-libgl
