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

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