+config EFI
+	bool "Support running U-Boot from EFI"
+	depends on X86
+	help
+	  U-Boot can be started from EFI on certain platforms. This allows
+	  EFI to perform most of the system init and then jump to U-Boot for
+	  final system boot. Another option is to run U-Boot as an EFI
+	  application, with U-Boot using EFI's drivers instead of its own.

+config EFI_APP
+	bool "Support running as an EFI application"
+	help
+	  Build U-Boot as an application which can be started from EFI. This
+	  is useful for examining a platform in the early stages of porting
+	  U-Boot to it. It allows only very basic functionality, such as a
+	  command prompt and memory and I/O functions. Use 'reset' to return
+	  to EFI.

+config EFI_RAM_SIZE
+	hex "Amount of EFI RAM for U-Boot"
+	depends on EFI_APP
+	default 0x2000000
+	help
+	  Set the amount of EFI RAM which is claimed by U-Boot for its own
+	  use. U-Boot allocates this from EFI on start-up (along with a few
+	  other smaller amounts) and it can never be increased after that.
+	  It is used as the RAM size in with U-Boot.
