From 7f772fbcc04b8f70a70b79f869b03c2897ba0651 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Sat, 1 Aug 2020 02:56:45 +0800 Subject: [PATCH] ARM: add Kconfig option for PSCI 0.1 We still have some platforms that only implements functionalities in PSCI 0.1 (e.g. Allwinner ARMv7 SoCs). Add a Kconfig option for exporting only PSCI 0.1. The code to export PSCI 0.1 is still available and gets activated by this patch. In addition, default ARCH_SUNXI U-Boot PSCI implementation to export PSCI 0.1, to fix poweroff/reboot regression on Allwinner multi-core ARMv7 SoCs.
