From: Anup Patel
Date: Mon Mar 15 2021 - 07:06:31 EST


This series adds SBI SRST extension support to Linux RISC-V.

These patches can be found in riscv_sbi_srst_v6 branch at:
https://github.com/avpatel/linux

Changes since v5:
- Factored-out pr_info() related change into separate patch
- Added cover letter

Changes since v4:
- We should compare both major and minor number to ensure that
SBI spec version is 0.3 (or above) for detecting SRST extension.

Changes since v3:
- Rebased on Linux-5.12-rc1
- Check SBI spec version when probing for SRST extension

Changes since v2:
- Rebased on Linux-5.10-rc5
- Updated patch as-per SBI SRST extension available in the latest
SBI v0.3-draft specification

Changes since v1:
- Updated patch as-per latest SBI SRST extension draft spec where
we have only one SBI call with "reset_type" parameter

RISC-V: Don't print SBI version for all detected extensions
RISC-V: Use SBI SRST extension when available
