Summary
=======

This document covers various features of the 'omap5_uevm' build and some
related uses.

eMMC boot partition use
=======================

It is possible, depending on SYSBOOT configuration to boot from the eMMC
boot partitions using (name depending on documentation referenced)
Alternative Boot operation mode or Boot Sequence Option 1/2.  In this
example we load MLO and u-boot.img from the build into DDR and then use
'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to
set boot0 as the boot device.
U-Boot # setenv autoload no
U-Boot # usb start

U-Boot # tftp ${loadaddr} omap5uevm/MLO
U-Boot # mmc write ${loadaddr} 0 100
U-Boot # tftp ${loadaddr} omap5uevm/u-boot.img
U-Boot # mmc write ${loadaddr} 300 400
