[PATCH v2 18/18] target/arm: Enable MVE in Cortex-M55


From: Peter Maydell
Subject: [PATCH v2 18/18] target/arm: Enable MVE in Cortex-M55
Date: Thu, 26 Aug 2021 14:17:25 +0100

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.
