Subject: [PATCH v2 03/14] target/arm: Add isar_feature tests for PAN + ATS1E1
Date: Sat,  1 Feb 2020 17:04:28 -0800	[thread overview]
Message-ID: <20200202010439.6410-4-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200202010439.6410-1-richard.henderson@linaro.org>

Include definitions for all of the bits in ID_MMFR3.
We already have a definition for ID_AA64MMFR1.PAN.
