From 3dc0a66d26bfc3820ab46aaf245cabf26fcf1eb4 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Mon, 9 Nov 2015 17:47:17 +1100 Subject: [PATCH] spapr: Add /system-id Section B.6.2.1 Root Node Properties of PAPR specification defines a set of properties which shall be present in the device tree root, one of these properties is "system-id" which "should be unique across all systems and all manufacturers". Since UUID is meant to be unique, it makes sense to use it as "system-id". This adds "system-id" property to the device tree root when not empty.
