X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PULL 02/32] target/arm: Add "_S" suffix to the secure version of a sysreg 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+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" From: Abdallah Bouassida This is a preparation for the coming feature of creating dynamically an XML description for the ARM sysregs. Add "_S" suffix to the secure version of sysregs that have both S and NS views Replace (S) and (NS) by _S and _NS for the register that are manually defined, so all the registers follow the same convention.
