From 62149f3564c5a59cb42834cbe97e6f36ad81a029 Mon Sep 17 00:00:00 2001 From: Atish Patra Date: Wed, 4 Nov 2020 16:04:36 -0800 Subject: [PATCH] RISC-V: Initialize SBI early Currently, SBI is initialized towards the end of arch setup. This prevents the set memory operations to be invoked earlier as it requires a full tlb flush. Initialize SBI as early as possible.
