Revision 3dbcea54b3ff706c58f8e8d4470f5e5d3d24a6a0 authored by Mark Rutland on 15 March 2019, 12:22:36 UTC, committed by Catalin Marinas on 19 March 2019, 14:54:24 UTC
Fujitsu erratum 010001 applies to A64FX v0r0 and v1r0, and we try to handle either by masking MIDR with MIDR_FUJITSU_ERRATUM_010001_MASK before comparing it to MIDR_FUJITSU_ERRATUM_010001. Unfortunately, MIDR_FUJITSU_ERRATUM_010001 is constructed incorrectly using MIDR_VARIANT(), which is intended to extract the variant field from MIDR_EL1, rather than generate the field in-place. This results in MIDR_FUJITSU_ERRATUM_010001 being all-ones, and we only match A64FX v0r0. This patch uses MIDR_CPU_VAR_REV() to generate an in-place mask for the variant field, ensuring the we match both v0r0 and v1r0.
