Subject: [PULL 23/51] target/arm: Enable MVE in Cortex-M55
Date: Wed,  1 Sep 2021 11:36:25 +0100	[thread overview]
Message-ID: <20210901103653.13435-24-peter.maydell@linaro.org> (raw)
In-Reply-To: <20210901103653.13435-1-peter.maydell@linaro.org>

We now have a complete MVE emulation, so we can enable it in our
Cortex-M55 model by setting the ID registers to match those of a
Cortex-M55 with full MVE support.
