lib/charset.c is not optional for
EFI_APP || EFI_LOADER || UFS || UT_UNICODE.
These must select CONFIG_CHARSET.

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.

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.

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!

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.
