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