[U-Boot] [PATCH v3 0/3] Handling of EFI application exit

[Heinrich Schuchardt]

EFI applications may proceed to loading and starting an operating system.
In this case they do not return to OpenWrt.

On the other hand they may return to OpenWrt. In this case they may
either call EFI_BOOT_SERVICES.Exit of return directly with a status code.

The first patch ensures correct handling of applications returning without
calling EFI_BOOT_SERVICES.Exit.

The second patch was split of the first version of the third. It contains
the definition of all return codes of the UEFI standard.

The third patch is necessary to output the actual status code of the
EFI application.
