Thanks Ard for the contribution, I will try to have a look later this week.
Some quick comments: - Which version of EDK2 should apply the patchset? I suspect the patchset will not apply... I saw some KVM comments in the timer patches that were not part of the patch. - I will probably need a new patchset with 'Contributed-under: TianoCore Contribution Agreement 1.0' added to the commit message to make sure you agree with the Tianocore contribution agreement. See Tianocore contribution agreement. - I would be happy to test your patchset. Do you have any instructions? - I had some FDT comments, But I have just addressed them in my previous email.
