afaict, QAEP is AOSP + qcom HAL's (ie. camera, vidc, gralloc/hwcomp, etc)..

Since camera/vidc is missing in upstream kernel, and gralloc/hwcomp
are the parts we want to replace, it may be easier to ignore QAEP..
or at least focus on AOSP (and look to what they do in QAEP for
debugging when things aren't working ;-))

fwiw, ifc6410 (and nexus4 and a fair number of other boards.. anything
with apq80XY) do *not* have integrated modems.. so IMHO they should be
valid targets for replicant..

hmm, yeah.. maybe better to focus on AOSP (and possibly CM).. at the
end of the day, if it ends up in AOSP then it should eventually
trickle into these other projects when they rebase (afaiu)
