From af965acc81796c0006c0200129cd22a27c714e52 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Wed, 12 Dec 2012 19:16:59 +0000 Subject: ARM: opcodes: add opcodes definitions for ARM security extensions The ARM security extensions introduced the smc instruction, which is not supported by all versions of GAS. This patch introduces opcodes-sec.h, so that smc is made available in a similar manner to hvc.
