From e491e15a3f4bdf7e22d5e448c3f0cfb733a8dd8b Mon Sep 17 00:00:00 2001 From: Leo Yu-Chi Liang Date: Mon, 29 Jun 2020 16:27:28 +0800 Subject: [PATCH] riscv: Fix linking error when building u-boot-spl with no SMP support Switch off SMP support when building u-boot-spl would cause linking error as follow: undefined reference to 'secondary hart relocate' and 'smp_call_function'. Add macro to wrap up proper code region that needs SMP configuration on.
