From de343bb632a123d7c2286e62267d6866a6b9e5f3 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 2 Mar 2018 10:45:39 +0000 Subject: hw/misc/iotkit-secctl: Arm IoT Kit security controller initial skeleton The Arm IoT Kit includes a "security controller" which is largely a collection of registers for controlling the PPCs and other bits of glue in the system. This commit provides the initial skeleton of the device, implementing just the ID registers, and a couple of read-only read-as-zero registers.
