I finally got a chance to spend some time with an Armada-3720-based Espressobin, and immediately faced a number of issues which would make the system of limited use for me. Fortunately, these are pretty easy to fix: - The first patch (already posted a couple of weeks ago, and included here for completeness) fixes what is probably a copy-paste issue between GICv2 and GICv3-based platforms, where a cpu-mask is wrongly applied to PPIs. - The following two patches add missing properties that are required for enabling virtualisation support (GIC maintenance interrupt, MMIO regions for GICv2 guest compatibility). KVM now runs correctly on this HW. - The following patch exposes the CPUs' PMUv3, making perf work. Hey, for once it is wired correctly, without anything funky breaking the interrupt routing! Let's not miss this once in a lifetime opportunity! - The last patch enables the USB2 interface on the Espressobin. OK, not very useful, but since it works... This has been tested on -next as of this yesterday.
All applied on mvebu/dt64-for-4.14 Thanks, Gregory
