Subject: [PATCH v2 04/25] arm64: cputype: Add CPU implementor & types for the Apple M1 cores
Date:   Mon, 15 Feb 2021 21:16:52 +0900
Message-Id: <20210215121713.57687-5-marcan@marcan.st>
In-Reply-To: <20210215121713.57687-1-marcan@marcan.st>

The implementor will be used to condition the FIQ support quirk.

The specific CPU types are not used at the moment, but let's add them
for documentation purposes.
