From 9f5b6e1b74c8289050836abdfb9c2539380f9105 Mon Sep 17 00:00:00 2001 From: Curtis Dunham Date: Thu, 7 Sep 2017 16:13:54 -0500 Subject: arm: make Arm GenericTimer a ClockedObject Within a device tree, the GenericTimer device needs to point (via phandle) to a clock domain which is itself also an object in the device tree. Within gem5, clock domains are managed by making all clocked SimObjects inherit from ClockedObject rather than SimObject. Without this change, the GenericTimer is unable to generate the appropriate clock domain phandle, and will crash during DTB autogeneration.
