From 9ec3921c028932aef7b3470dfbecebd11841f4a6 Mon Sep 17 00:00:00 2001 From: Jonathan Wright Date: Wed, 28 Mar 2018 15:52:03 +0100 Subject: Check presence of fix for errata 843419 in Cortex-A53 A fix for errata 843419 may be available in revision r0p4 of the Cortex-A53 processor. The presence of the fix is determined by checking bit 8 in the REVIDR register. If the fix is present we report ERRATA_NOT_APPLIES which silences the erroneous 'missing workaround' warning.
