Hi Bin,

Thanks a lot. Now it built.
It built, but I didn't get much further :-(
I'm running qemu 2.1.3 on OpenSUSE and it doesn't seem to start in EFI mode other than with a build of the Open Virtual Machine Firmware that I found googling [1]. With this I can reach an EFI shell.
I tried both the BIOS that qemu would load by default and the one that the Testing page of the qemu wiki [2] provides [3] but they get stuck at some point that doesn't generate any output.
Anyway, with the OVMF, I am able to see the EFI BIOS starting. I can list the block devices and also see the file containing U-Boot in payload format (u-boot-payload.efi) This is how I start qemu:
qemu-system-x86_64 -nographic -bios ../bios/OVMF.fd -hda fat:tmp/efi/
It tries to boot from any of the boot devices available, then it fails and drops me to the Shell.
At which point, following the README.efi, I launch the payload:
FS0:u-boot-payload.efi
I get a message: U-Boot EFI Payload
which seems to indicate that something is happening, but nothing else.
Almost immediately the screen blanks and I get the usual sequence of Boot Failed messages that show which boot devices the BIOS tried.
Shouldn't I get the same interactive prompt that I see when using non-EFI mode?
