The repos might need to be reorganized to have yet another layer of inheritance like what was done for Wifi vs. 3G Note 10.1 units
e.g. instead of
fusion3-common->yuga odin pollux
fusion3-common->yuga odin pollux-common->pollux_wifi pollux_3g
and please please please don't use the "inherit part of a repo" mess that p31xx devices use... Figuring out which parts of p3100 are common and which aren't is always such a pain in the ass.
The build with the phone stuff still in it however works enough for me to keep it as daily driver. Broken for me is NFC for now (haven't tested HDMI yet).
