Hello Bin, Simon,

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.
Almost the same also with qemu 2.2.0 on Ubuntu

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
I have added some traces to the code. It seems that the failure happens at lib/efi/efi_stub.c:333 where it tries to get a memory map for the 2nd time.

Tomorrow I'll try again, after downloading and trying the latest qemu.
What version of qemu is known to work with the EFI x86 payload?
I'm using 2.3.90.
Although there may be a dependency on EFI also. I found that the binary I downloaded, plus the two I built, worked OK.
