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")
