n1sdp: update n1sdp pci quirk for SR-IOV support
Upstream-Status: Inappropriate [will not be submitted as its a work around to address the hardware issue]
Signed-off-by: Khasim Syed Mohammed <khasim.mohammed@arm.com>
VFs are not probing the vendor ID first, which is otherwise
the gate keeper for undiscovered devices. So any accesses using
a config space offset greater than 0 must be coming for an
already discovered device or from a VF that has just been created.
Also if Linux already has a struct pci_dev* for a given BDF,
this device is safe to access.
Skip the firmware table in these cases and allow accesses to
those devices. That enables SR-IOV support on the N1SDP board.
