It looks like the TI wifi drivers really are non-free since they require extracting stuff from binary files in order to compile the firmware

It's a mostly but not entirely free system which according to the Debian wiki requires a non-free compiler to build. VirtualBox also isn't available on Parabola. If it becomes a fully free system at some time in future then this patch can be reverted.

The relevant quote is 'Boot blobs are in binary format (Limited by Amlogic's policy)'

This reverts commit 975de7039c56dbb532eeccb80396bd6e8c441827.

Based on freedom-maker with proprietary
stuff removed
