[U-Boot] Support of latest qemux86-64

Hi all,

I'm trying to use u-boot (v2017.01) with qemu-system-x86_64 v2.10.0 and run into a "trying to execute code outside of RAM or ROM at xxxxx" issue. It happens both when I build and use u-boot as a bios and as EFI payload, just the addresses in the error message are different. On qemu v2.5.0 at least EFI option works fine.

I understand that it can be (and probably is) a QEMU issue, but maybe someone on the list already encountered it and knows a workaround or has successfully used u-boot with QEMU >=2.10.0 and can share their experience.

Thanks in advance.

Best regards, Anton Gerasimov
