That is correct, you should just recompile the DTB; no need to recompile gem5

I think the problem lies in the DTB and more specifically in the range mapping
https://github.com/gem5/gem5/blob/stable/system/arm/dt/platforms/vexpress_gem5_v1_base.dtsi#L70
Could you replace the third
argument from cmdline)
Please let me know if it works

I haven't looked at this closely, but it's normal for the values in the BARs

Giacomo,
That's good to know.
We're running `fs.py` with `system/arm/dt/armv7_gem5_v1_1cpu.dtb` which we've
copied into our working directory.

Out of curiosity, which DTB are you using?
IMO the kernel shouldn't write 800 to the PCI Bar, knowing there is DRAM
there and this is notified via the DTB

Are you using up to date develop? There was a bug like this a while ago, but
it's been fixed on develop for a while as well.
