12ed980b8cSAlexander Graf	  Select this option if you want to run EFI applications (like grub2)
13ed980b8cSAlexander Graf	  on top of U-Boot. If this option is enabled, U-Boot will expose EFI
14ed980b8cSAlexander Graf	  interfaces to a loaded EFI application, enabling it to reuse U-Boot's
15ed980b8cSAlexander Graf	  device drivers.
