From f25006b96e9f6b9b8688ec8e4bc8a87dc1f1479d Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Tue, 13 Mar 2018 16:50:30 +0000 Subject: [PATCH] optee: Add CONFIG_OPTEE_LOAD_ADDR CONFIG_OPTEE_LOAD_ADDR is used to tell u-boot where to load the OPTEE binary into memory prior to handing off control to OPTEE. We need to pull this value out of u-boot in order to produce an IMX IVT/CSF signed pair for the purposes of secure boot. The best way to do that is to have CONFIG_OPTEE_LOAD_ADDR appear in u-boot.cfg. Adding new CONFIG entires to u-boot should be kconfig driven so this patch does just that.
