From bb48711800e6d7aedbf4dfd3367e0ab1270a6bea Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 13 Dec 2017 14:19:37 -0800 Subject: arm64: cpu_errata: Add Kryo to Falkor 1003 errata The Kryo CPUs are also affected by the Falkor 1003 errata, so we need to do the same workaround on Kryo CPUs. The MIDR is slightly more complicated here, where the PART number is not always the same when looking at all the bits from 15 to 4. Drop the lower 8 bits and just look at the top 4 to see if it's '2' and then consider those as Kryo CPUs. This covers all the combinations without having to list them all out.
