You can configure any ARM machine to use firmware blob instead of kernel + device tree. This way it looks more like a real machine.
I don't have any "blob" I can only run virt.

We ran it on virt, for example.
And how did you accessed the register and for what purpose?
What should be the expected outcome.
Kind regards,

In general I can't release something that I don't understand and can't test.
