From 282a48eca4c84c3f146165aab3a64e82b4b60670 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 6 Feb 2024 13:29:21 +0000 Subject: [PATCH] target/arm: Add Cortex-R52 IMPDEF sysregs Add the Cortex-R52 IMPDEF sysregs, by defining them here and also by enabling the AUXCR feature which defines the ACTLR and HACTLR registers. As is our usual practice, we make these simple reads-as-zero stubs for now.
