Description
I have a PCI ISA bridge on one of my old laptop, so I wrote a header file for the National Semiconductor PC87200 chip (no idea, if I have this one on my computer). Chip is PCI 2.1 and 2.2 compliant, so it is hardly usable without modification of the Haiku's present PCI code. Code is still hardware untested. We should elaborate it more. Intel's PCI to ISA bridge is from the year 2000 (I think) and I do not know, if it is compatible with this device. More information: https://newscenter.ti.com/news-releases?item=125553
I added also a test to check that typdef structs are right size. :)
To prevent conflicting solutions I will enclose also one Google pantent pdf, that can be actual.

Please do not attach patches to Trac. Submit them to Gerrit at http://review.haiku-os.org instead.
I don't understand how you can not be sure which device you have. Just look at listdev, if it's a PCI device it will be listed there.

Sorry, I did not know that. I understood "Has a Patch:" that I can put patches here. :)

There is no "Has a patch" anymore. We changed our workflow.
OK, I updated my GitHub profile, but I need Contributor rights to send a patch, I suppose. I have now a public ssh key with the profile. SSH key can be used to sign patches, if I remember right. But I hope that the present patch enclosed here is enough.

You do not need contributors right. Anyone can submit patches on Gerrit. Do not use Trac for this, patches sent here will likely be lost.
The instructions to submit patches are here: https://dev.haiku-os.org/wiki/CodingGuidelines/SubmittingPatches
Let us know if anything is unclear, we can improve the document.
A patch for PCI-to-ISA header file and test file.
