From bf433afd60ce2ccd1bec3cf14150323be8272ac3 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Sat, 12 Jul 2014 14:24:02 +0100 Subject: ARM: HYP/non-sec: add separate section for secure code In anticipation of refactoring the HYP/non-secure code to run from secure RAM, add a new linker section that will contain that code. Nothing is using it just yet.
