Mats,
The team is just now rebasing the bringup work on 3.8.4. You can find
their work here:
http://arago-project.org/git/projects/?p=linux-keystone.git;a=shortlog;h=refs/heads/release-server/master
(The word "server" ~= 3.8 for this archive)
Please note that all the master branches are rebuilt from the feature
branches in the nightly build script. I think the feature branches get
rebased also. The tags of course you can count on.
The A15's use the per-core archetecture timer normally. However the SOC
has multiple (20) Timer64 peripherals that can be used as well if they
are not being used by the DSPs. If you configure which timer64 to use
w/ device tree you should be fine.
