From 43df0a159df6ef4c627553915634cd3d961d4da8 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Wed, 18 Mar 2020 09:22:49 +0100 Subject: [PATCH] stm32mp1: dynamically detect op-tee presence Activate OP-TEE driver for trusted and optee defconfig. This driver allows detection of TEE presence for boot from flash; CONFIG_STM32MP1_OPTEE is also removed.
