From 1cf45b8fdbb87040e1d1bd793891089f4678aa41 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 31 Oct 2019 14:47:25 -0700 Subject: arm64: apply ARM64_ERRATUM_843419 workaround for Brahma-B53 core The Broadcom Brahma-B53 core is susceptible to the issue described by ARM64_ERRATUM_843419 so this commit enables the workaround to be applied when executing on that core. Since there are now multiple entries to match, we must convert the existing ARM64_ERRATUM_843419 into an erratum list and use cpucap_multi_entry_cap_matches to match our entries.
