The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE and this makes it imposible to use CONFIG_VAL(). Rename it to resolve this problem. Signed-off-by: Simon Glass <sjg@chromium.org> |

Overview of SPL verified boot on powerpc/mpc85xx & arm/layerscape platforms =========================================================================== Introduction ------------ This document provides an overview of how SPL verified boot works on powerpc/ mpc85xx & arm/layerscape platforms. Methodology ----------- The SPL image is responsible for loading the next stage boot loader, which is the main u-boot image. For secure boot process on these platforms ROM verifies SPL image, so to continue chain of trust SPL image verifies U-boot image using spl_validate_uboot(). This function uses QorIQ Trust Architecture header (appended to U-boot image) to validate the U-boot binary just before passing control to it.
