Asus F2A85-M: Activate IOMMU support
Activate the IOMMU support for the Asus F2A85-M, by enabling it in `buildOpts.c` and by adding the device to `devicetree.cb`.
The device shows up in the output of `lspci`.
$ lspci -s 0.2 […] 00:00.2 IOMMU: Advanced Micro Devices [AMD] Family 15h (Models 10h-1fh) I/O Memory Management Unit
The Linux kernel is also able to set it up.
