Subject: [PATCH v3 10/13] arm64: cputype: Add missing MIDR values for Cortex-A72 and Cortex-A75
Date: Mon, 8 Jan 2018 17:32:35 +0000 [thread overview]
Message-ID: <1515432758-26440-11-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1515432758-26440-1-git-send-email-will.deacon@arm.com>
Hook up MIDR values for the Cortex-A72 and Cortex-A75 CPUs, since they
will soon need MIDR matches for hardening the branch predictor.
