EFI Support
-----------
U-Boot supports booting as a 32-bit or 64-bit EFI payload, e.g. with UEFI.
This is enabled with CONFIG_EFI_STUB. U-Boot can also run as an EFI
application, with CONFIG_EFI_APP. The CONFIG_EFI_LOADER option, where U-Booot
provides an EFI environment to the kernel (i.e. replaces UEFI completely but
provides the same EFI run-time services) is not currently supported on x86.
See README.efi for details of EFI support in U-Boot.
