+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.

+ 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.

+ help
+ EFI does not support mixing 32-bit and 64-bit modes. This is a
+ significant problem because it means that you must build a stub with
+ the correct type for EFI to load it correctly. If you are using
+ 32-bit EFI, select 32-bit here, else select 64-bit. Failure to do
+ this may produce no error message - it just won't start!
