You can create and install PKGBUILDs from the Mali sources at malideveloper.com. You want the UMP and X11 display drivers. This will work but you will not have hardware acceleration.
In order to get 3D acceleration you also need libMali. Building libMali requires the proprietary Mali DDK:

https://aur.archlinux.org/packages/sunxi-mali-git/. Once installed you may have to manually symlink /lib/libMali.so to point to /lib/libEGL.so.1.0.0, /lib/libGLESv1_CM.so.1.1.0, and /lib/libGLESv2.so.2.0.0.
