Subject: [PATCH RFC 1/2] RISC-V: define the elements of the VCSR vector CSR
Date: Tue, 28 Feb 2023 22:54:34 +0100	[thread overview]
Message-ID: <20230228215435.3366914-2-heiko@sntech.de> (raw)
In-Reply-To: <20230228215435.3366914-1-heiko@sntech.de>

From: Heiko Stuebner <heiko.stuebner@vrull.eu>

The VCSR CSR contains two elements VXRM[2:1] and VXSAT[0].

Define constants for those to access the elements in a readable way.
