Subject: [PATCH v4 04/18] arm64: cputype: Add CPU implementor & types for the Apple M1 cores
Date: Fri,  2 Apr 2021 18:05:28 +0900	[thread overview]
Message-ID: <20210402090542.131194-5-marcan@marcan.st> (raw)
In-Reply-To: <20210402090542.131194-1-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.

Acked-by: Will Deacon <will@kernel.org>
