From 7e249bc13aaf204a08e70044ebba04f404f6cf85 Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Tue, 21 Apr 2020 14:51:57 -0700 Subject: riscv: Move all SMP related SBI calls to SBI_v01 SMP support for S-mode U-Boot is enabled only if SBI_V01 is enabled. There is no point in supporting SMP related (IPI and fences) SBI calls when SBI_V02 is enabled. Modify all the SMP related SBI calls to be defined only for SBI_V01.
