This is the first device the virt board selects:
config ARM_VIRT
bool
imply PCI_DEVICES
imply TEST_DEVICES
imply VFIO_AMD_XGBE
imply VFIO_PLATFORM
imply VFIO_XGMAC
imply TPM_TIS_SYSBUS
select A15MPCORE

Yes, agreed. This surgical change was quicker for my testing, but we
don't need this patch right now, so let's drop it.
