+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.
