bool "Support running U-Boot from EFI"
depends on X86
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.

bool "Support running as an EFI application"
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
hex "Amount of EFI RAM for U-Boot"
depends on EFI_APP
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.
