From ffdf9f9ae057131375534df5f1e798d1e64785e9 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 21 Apr 2015 07:18:35 +0200 Subject: tegra124: Add PSCI support for Tegra124 This is based on Thierry Reding's work and uses Ian Campell's preparatory patches. It comes with full support for CPU_ON/OFF PSCI services. The algorithm used in this version for turning CPUs on and off was proposed by Peter De Schrijver and Thierry Reding in http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/210881. It consists of first enabling CPU1..3 via the PMC, just to powergate them again with the help of the Flow Controller. Once the Flow Controller is in place, we can leave the PMC alone while processing CPU_ON and CPU_OFF PSCI requests.
