Beware - the machine is rather aged and slow by todays standards ((c)git
is rather heavy weight):

The xf86-video-armada.git tree is not trivial to build as there's
dependencies on the Vivante galcore libraries - and even if you have
them, there's then there's non-trivial changes to the kernel-side driver
to support dmabuf imports.  Welcome to the world of closed source graphics
libraries making open source hard... I've been wishing for etnaviv for
a while now...

Even though the kernel side is supposed to be GPL, I'm really not happy
distributing it or publishing changes as there are a number of files with
headers which seem to be GPL-incompatible (which I've eliminated from my
tree through updates) but the problem is wonderful git keeps them as
history... and in my tree it's a massive 93 patches, against an old
version of the code (0.8.0.1998) which I then sort-of updated to the
version OLPC were carrying towards the start of 2013.

It's probably best if Sebastian walks you through getting it up and
running as my experience is with my kernels and userspace, which has all
the necessary hacks in.
