From db711893eac81442fb5cde3801e183d3abfe5693 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Thu, 2 Jan 2020 16:19:40 -0500 Subject: ARM: OMAP2+: Add omap_secure_init callback hook for secure initialization This can be used for detecting secure features or making early device init sequence changes based on device security type.
