From 1e0e11085a0d3e47cbbad8944f70b371d22b987d Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 22 Jan 2020 15:50:42 +1100 Subject: spapr: Move creation of ibm,architecture-vec-5 property This is currently called from spapr_dt_cas_updates() which is a hang over from when we created this only as a diff to the DT at CAS time. Now that we fully rebuild the DT at CAS time, just create it along with the rest of the properties in /chosen.
