Marek VasutandHeinrich Schuchardt dc3765ede5 doc: Switch from setenv to env set

The "env" command is the recommended environment management command,
its "set" subcommand is the equivalent replacement for legacy "setenv"
command. Update the documentation to use the contemporary "env set"
command instead of legacy "setenv" command.

Note that the "setenv" command is unlikely to be removed from U-Boot
in the near future due to it being integral part of the command line
ABI.

Implemented using:
$ sed -i 's@\<setenv\>@env set@g' $(git grep -li '\<setenv\>' doc/) README

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.
