There is no requirement that every SOC handle UEFI partitions.  The
Beagle board uses a TI OMAP3530, and the Origen Board uses a Samsung
Exynos 4 Quad. To my knowledge UEFI Partition support is not a feature
found on either SoC.Instead what happens is the EFI/UEFI loader takes
the place of Daz U-Boot and functions similarly to the DUET package
that was created for x86/x86_64 based systems in order to allow these
systems to develop EFI/UEFI enabled operating systems.
