From 001b3cab51ebfcb13e8dd03ea25bfa3bd0c517a3 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 20 Mar 2017 12:41:44 +0000 Subject: [PATCH] arm: HVC and SMC encodings don't exist for M profile MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit M profile doesn't have the HVC or SMC encodings, so make them always UNDEF rather than generating calls to helper functions that assume A/R profile.
