From aa50479b4f8adc8d4f0744a2d060f6e5c014d279 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 4 Jul 2022 18:02:49 +0100 Subject: arm64/sysreg: Add _EL1 into ID_AA64ISAR1_EL1 definition names Normally we include the full register name in the defines for fields within registers but this has not been followed for ID registers. In preparation for automatic generation of defines add the _EL1s into the defines for ID_AA64ISAR1_EL1 to follow the convention. No functional changes.
