Subject: [PATCH v4 01/11] dt-bindings: riscv: add Zca, Zcf, Zcd and Zcb ISA extension description
Date: Mon, 29 Apr 2024 17:04:54 +0200 [thread overview]
Message-ID: <20240429150553.625165-2-cleger@rivosinc.com> (raw)
In-Reply-To: <20240429150553.625165-1-cleger@rivosinc.com>
Add description for Zca, Zcf, Zcd and Zcb extensions which are part the
Zc* standard extensions for code size reduction. Additional validation
rules are added since Zcb depends on Zca, Zcf, depends on Zca and F, Zcd
depends on Zca and D and finally, Zcf can not be present on rv64.
