Subject: [PATCH v2 11/21] target/arm: Move DBGDIDR into ARMISARegisters
Date: Fri, 14 Feb 2020 17:51:06 +0000 [thread overview]
Message-ID: <20200214175116.9164-12-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200214175116.9164-1-peter.maydell@linaro.org>
We're going to want to read the DBGDIDR register from KVM in
a subsequent commit, which means it needs to be in the
ARMISARegisters sub-struct. Move it.
