From 0e0456ab8895a5e85998904549e331d36c2692a5 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 24 Aug 2018 13:17:36 +0100 Subject: [PATCH] target/arm: Implement RAZ/WI HACTLR2 The v8 AArch32 HACTLR2 register maps to bits [63:32] of ACTLR_EL2. We implement ACTLR_EL2 as RAZ/WI, so make HACTLR2 also RAZ/WI. (We put the regdef next to ACTLR_EL2 as a reminder in case we ever make ACTLR_EL2 something other than RAZ/WI).
