Hi, im trying to run u-boot as uefi-payload for qemu this works totally fine. My real target is a Minnowboard Turbot. I did use the minnowmax_defconfig enabled CONFIG_EFI, CONFIG_EFI_STUB and CONFIG_EFI_STUB_64BIT. The Board has the latest uefi by Intel installed(0.93, X64).
When i load U-Boot as payload for the board-uefi the efi_main function gets executed but the call to "cpu_call32" seems to get stuck ( i think its at the "retf" arch/x86/cpu/call32.S:37).
