From 83f192d34d2525f9c0053c2179bdbc69327b9158 Mon Sep 17 00:00:00 2001 From: Suraj Jitindar Singh Date: Mon, 6 May 2019 11:48:03 +1000 Subject: [PATCH] target/ppc: Add ibm,purr and ibm,spurr device-tree properties The ibm,purr and ibm,spurr device tree properties are used to indicate that the processor implements the Processor Utilisation of Resources Register (PURR) and Scaled Processor Utilisation of Resources Registers (SPURR), respectively. Each property has a single value which represents the level of architecture supported. A value of 1 for ibm,purr means support for the version of the PURR defined in book 3 in version 2.02 of the architecture. A value of 1 for ibm,spurr means support for the version of the SPURR defined in version 2.05 of the architecture. Add these properties for all processors for which the PURR and SPURR registers are generated.
