+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.
Please use "U-Boot"
This seems a bit brief. Are there instructions on how to actually set it up?
