[PATCH v3 11/14] RISC-V: Set minimum priv version for Zfh to 1.11
Posted by Christoph Muellner 2 years, 5 months ago
From: Christoph Müllner <christoph.muellner@vrull.eu>

There are no differences for floating point instructions in priv version 1.11
and 1.12. There is also no dependency for Zfh to priv version 1.12.
Therefore allow Zfh to be enabled for priv version 1.11.
