X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PULL 13/52] target/arm: Implement RAZ/WI HACTLR2 X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail: RDMRC_1 RSF_0 Z_629925259 SPT_0 Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" 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).
