From bc3d3447b66a9eb398c7cce96f05b7c78d725abc Mon Sep 17 00:00:00 2001 From: Daniel Thompson Date: Tue, 19 Sep 2017 19:32:04 +0100 Subject: arm64: dts: foundation-v8: Enable PSCI mode Currently if the Foundation model is running ARM Trusted Firmware then the kernel, which is configured to use spin tables, cannot start secondary processors or "power off" the simulation. After adding a couple of labels to the include file and splitting out the spin-table configuration into a header, we add a couple of new headers together with two new DTs (GICv2 + PSCI and GICv3 + PSCI). The new GICv3+PSCI DT has been boot tested, the remaining three (two of which existed prior to this patch) have been "tested" by decompiling the blobs and comparing them against a reference.
