I see. We can't rely on CyanogenMod, we'll have to make it work with AOSP.

Your instructions seem like a bit of fidling, especially when finding the
"LLVMLinux approved commit" to revert to, but it should be feasible. I'll
talk to Bero if he can fit that into AOSP.

Yeap. Nexus 7.

So, at Linaro, we can't test Nexus 7 because it's NVidia, which is not a
Linaro member. I know it's silly, but I don't make the rules. Also, would
be good to have the main reference platform on something a bit more
friendly than a phone-factor. I'm thinking of using the new Arndale as the
standard (Octo-Big/Little Exynos 5 5420, 3GB RAM), but since the builds are
on a per-device basis, we might have to fiddle the LAVA jobs to use the
same process to produce different binaries.

I hope AOSP doesn't have any device-specific stuff, and it's only in the

We have to work on making a check-point at least once a month, preferably

I agree this is not optimal. I was expecting to have separate builds from
the kernel and the system, so that we can mix&match.
