There is a problem with reading Windows DTB from lowstub
on AMD platform B650 chipset I'm unable to read lowest range 0x1000 due unknown reason

If I skip the lowest range I don't get the errors as above, however with skipping, the dtb is not found and I can't find processes in OS
IOMMU/PreBootProtection disabled
It worked fine on Intel platform and it's weird that that regions is somehow protected despite iommu disabled.
