From ba9456ac9c72a7a5d4d59340aba4259351832521 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Mon, 6 Jun 2011 17:56:49 +0530 Subject: ARM: OMAP: Add Secure HAL and monitor mode API infrastructure. On OMAP secure/emulation devices, certain APIs are exported by secure code. Add an infrastructure so that relevant operations on secure devices can be implemented using it. While at this, rename omap44xx-smc.S to omap-smc.S since the common APIs can be used on other OMAP's too.
