mppb -- Prometheus PCI bridge driver
mppb* at zbus0
pci* at mppb?
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.
The mppb device first appeared in NetBSD 6.0.
The mppb driver was written by Radoslaw Kujawa
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.
