Unfortunately the EFI x86 application and payload support have been broken for quite a while. This series addresses various bug fixes, plus several enhancements like toolchain compatibility (eg: kernel.org i386-linux-gcc), introduction of generic EFI payload which can run on any x86 board, and a EFI framebuffer driver for the payload.
This series is available at u-boot-x86/efi-working for testing.
