Sony AOSP for Z5 compact

Question

I'd like to build Oreo for my Z5 compact (suzuran, e5823). I started the instructions of Sony on their dev site.

Contrary to 7.0 and 6.0 at the time, when I'm prompted for the configuration, I cannot see my device.

Which would you like? [aosp_arm-eng]

I'm not sure if I can pick aosp_arm-eng, download binaries from sony for 7.0.1 and pray for the best.

I am to wait that they release a specific guide, or update their repos?
