[PATCH v2] arm: change vendor ID for virtio-mmio

Show all headers | View raw

ACPI spec 5.0 allows the use of PCI vendor IDs.

Since we have one for virtio, it seems neater to use that
rather than LNRO. For the device ID, use 103F which is a legacy ID that
isn't used in virtio PCI spec - seems to make sense since virtio-mmio is
a legacy device but we don't know the correct device type.

Guests should probably match everything in the range 1000-103F
(just like legacy pci drivers do) which will allow us to pass in the
actual ID in the future if we want to.
