Subject: [PATCH v2 12/12] target/arm: Enable FEAT_MOPS for CPU 'max'
Date: Tue, 12 Sep 2023 15:04:34 +0100 [thread overview]
Message-ID: <20230912140434.1333369-13-peter.maydell@linaro.org> (raw)
In-Reply-To: <20230912140434.1333369-1-peter.maydell@linaro.org>
Enable FEAT_MOPS on the AArch64 'max' CPU, and add it to
the list of features we implement.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
