From 573a3811edc89c2ea3bf4fd077e3673b863b9a0d Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 14 Apr 2017 11:10:24 +0900 Subject: sysreset: psci: support system reset in a generic way with PSCI If the system is running PSCI firmware, the System Reset function (func ID: 0x80000009) is supposed to be handled by PSCI, that is, the SoC/board specific reset implementation should be moved to PSCI. U-Boot should call the PSCI service according to the arm-smccc manner. The arm-smccc is supported on ARMv7 or later. Especially, ARMv8 generation SoCs are likely to run ARM Trusted Firmware BL31. In this case, U-Boot is a non-secure world boot loader, so it should not be able to reset the system directly.
