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.
11 prompt "Select EFI mode to use"
15 bool "Support running as an EFI application"
17 Build U-Boot as an application which can be started from EFI. This
18 is useful for examining a platform in the early stages of porting
19 U-Boot to it. It allows only very basic functionality, such as a
20 command prompt and memory and I/O functions. Use 'reset' to return
24 bool "Support running as an EFI payload"
29 hex "Amount of EFI RAM for U-Boot"
33 Set the amount of EFI RAM which is claimed by U-Boot for its own
34 use. U-Boot allocates this from EFI on start-up (along with a few
35 other smaller amounts) and it can never be increased after that.
36 It is used as the RAM size in with U-Boot.
39 prompt "EFI 32/64-bit selection"
42 EFI does not support mixing 32-bit and 64-bit modes. This is a
43 significant problem because it means that you must build a stub with
44 the correct type for EFI to load it correctly. If you are using
45 32-bit EFI, select 32-bit here, else select 64-bit. Failure to do
46 this may produce no error message - it just won't start!
49 bool "Produce a stub for running with 32-bit EFI"
52 bool "Produce a stub for running with 64-bit EFI"
