From 98dd64f34f47ce19b388d9015f767f48393a81eb Mon Sep 17 00:00:00 2001 From: Jens Wiklander Date: Mon, 4 Jan 2016 15:37:32 +0100 Subject: ARM: 8478/2: arm/arm64: add arm-smccc Adds helpers to do SMC and HVC based on ARM SMC Calling Convention. CONFIG_HAVE_ARM_SMCCC is enabled for architectures that may support the SMC or HVC instruction. It's the responsibility of the caller to know if the SMC instruction is supported by the platform. This patch doesn't provide an implementation of the declared functions. Later patches will bring in implementations and set CONFIG_HAVE_ARM_SMCCC for ARM and ARM64 respectively.
