Now I am able to reach the jump_to_uboot call

I reach this point by commenting out:
* the call to exit_boot_services
* the brace following the if (ret) test associated to exit_boot_services
* the enabling of the debug UART (because the qemu build is probably
not compatible with my board)

I have found a workaround to the problem I was describing in my first
mail, however the issue is not solved cleanly, because I'm not exiting
EFI Boot Services.

This might problem might by due to differences in the EFI firmware
between what runs on the NUC and Tianocore, which I use in Qemu.

I can create a bug report, if there is any bug tracker. From the
website I couldn't find any.
