The mppb driver provides support for the PCI bus present on Prometheus Zorro III to PCI bridge card.

The mppb driver supports the following hardware:
PROMETHEUS
Matay Prometheus. Manufacturer 44359, product 1.

pci(4)

The mppb device first appeared in NetBSD 6.0.

The mppb driver was written by Radoslaw Kujawa <radoslaw.kujawa@gmail.com>.

The hardware does not support DMA to host memory.

The Prometheus does not support repeating of PCI transactions, instead if the PCI card demands a retry of transaction, it returns value 0xFFFFFFFF. This is currently not handled by the mppb driver and will confuse some PCI card drivers.
