Programming the G-REX PCI bridge

The p5pb device first appeared in NetBSD 6.0.

The p5pb driver was written by Radoslaw Kujawa <radoslaw.kujawa@gmail.com>.

The NetBSD developers don't have access to G-REX hardware or documentation. Support for this device is based on best wishes.

Support for genfb(4) framebuffer on CVPPC/BVPPC needs more testing.

DMA to host memory is not supported. This is a driver limitation.
