From e360f4db072593893dcbbbdaa5d322f7d5061b34 Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Thu, 26 May 2016 17:33:38 +0100 Subject: [PATCH] arm: Make EL checks available in SE mode A lot of code assumes that it is possible to test what the highest EL is and if it is 64 bit. These calls currently don't work in SE mode since they rely on an instance of an ArmSystem.
