Hello,
 
The platform I'm building EDK2 for requires the IOMMU to be set up for= devices to access their own memory space, but there are multiple IOMMUs on= my platform and they need to be assigned to different devices. Does EDK2 n= atively support configuring multiple IOMMUs on the same platform and assign= ing them to a given device? If it does, how would I go about that?
 
Thanks,
Arminder
