I have been following the steps from
https://wiki.linaro.org/LEG/UEFIforQEMU
qemu-system-aarch64 \
-m 1024 \
-cpu cortex-a57 \
-M virt \
-bios QEMU_EFI.fd \
-serial stdio
I tried this steps with and without my patches and it resulted in the
same.
It seems like I am missing something in the qemu cli, do I need to pass
special dtb file or something similar ?
The above command line is not right ("-bios"). Please scroll down the
wiki page, to the section heading saying "Using persistent UEFI
variables". There it explains how to pad the images and how to use two
-pflash options. ... Perhaps even that part of the article is a bit
out-of-date now.
Basically, today ArmVirtQemu should be used the same way as OVMF, except
for the padding. The build produces two files:
- QEMU_EFI.fd (fw binary)
- QEMU_VARS.fd (varstore template)
Each should be padded to 64MiB with zeros at the end (write a small
script for that), then use them with two pflash drives similarly to OVMF.
Still no luck, you can see my log error [1]. I never get to UEFI shell,
I have
tried with and without virtio disk.

I will continuing googling ...
In order to get as detailed as possible logs, I suggest adding the
following option to the ArmVirtQemu build command line:
-D DEBUG_PRINT_ERROR_LEVEL=0x8040004F
The current log looks quite strange to me in places, but I'm not sure if
that's because there are problems in those parts, or because the log
does not contain DEBUG_VERBOSE entries.

I am using Ubuntu 16.04 for builds and runs
