Is there any ongoing work to support more than one Memory BAR?
From what I can tell, current implementation picks the first Memory
BAR, and uses it via pci_device.membase
That field exists merely as a convenience for drivers, since it's a
common pattern that drivers use only the first memory BAR.
Other BARs can easily be accessed via pci_bar_start(). For example, in
drivers/net/vmxnet3.c:
vmxnet->pt = ioremap ( pci_bar_start ( pci, VMXNET3_PT_BAR ),
VMXNET3_PT_LEN );
