From 678382c73a08145262e95b5639607f72e49c0ee9 Mon Sep 17 00:00:00 2001 From: Andre Heider Date: Fri, 9 Feb 2018 08:10:22 +0100 Subject: [PATCH] arm/PSCI: support PSCI versions greater than 1.0 ATF recently began announcing PSCI v1.1. Since that version is unknown to u-boot, the PSCI device nodes were not updated. Switch from the case statement to a greater/less-than comparison so that v1.1, as well as future versions, get at least the compatible nodes of known versions. PSCI v1.1 doesn't seem to have introduced a new corresponding compatible.
