Regarding PCIe peek/poke in NetBSD

[Gnanasekar Loganathan <l.gnanasekar%gmail.com@localhost>]

Hi All,

I'm new to NetBSD kernel.

In NetBSD how we can access the I/O region, Memory region and
Prefetchable region for any PCIe devices?
How to map this region and do peek/poke on those addresses?

Please advice.

Thanks,
Gnana
