          Select this option if you want to run EFI applications (like grub2)
          on top of U-Boot. If this option is enabled, U-Boot will expose EFI
          interfaces to a loaded EFI application, enabling it to reuse U-Boot's
          device drivers.

+         Some hardware does not support DMA to full 64bit addresses. For this
+         hardware we can create a bounce buffer so that payloads don't have to
+         worry about platform details.
