Revision d411cf02ed0260dacc4b2fd61dd5040fc2aa97e7 authored by Greentime Hu on 19 December 2019, 06:44:59 UTC, committed by Paul Walmsley on 20 December 2019, 11:32:24 UTC
This patch fixes that the sscratch register clearing in M-mode. It cleared sscratch register in M-mode, but it should clear mscratch register. That will cause kernel trap if the CPU core doesn't support S-mode when trying to access sscratch. Fixes: 9e80635619b5 ("riscv: clear the instruction cache and all registers when booting") Signed-off-by: Greentime Hu <greentime.hu@sifive.com> Reviewed-by: Anup Patel <anup@brainfault.org> Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>
