Add PCI support for the Vulcan board, supporting USB and CF ports. The PC/104 bus (actually a hack on the second CarBus slot) is not currently supported.

Thanks, I've applied both of them.

Krzysztof,

Is there any plan for this to be merged while the window is still opened? I have some other patches that depend on these first two, but if it's going to be delayed until 2.6.36, I'll simply repost the whole thing for review.

Cheers,

        M.

Who you jivin' with that Cosmik Debris?

Sure, I plan to send them to Linus shortly.

Hi Marc,
Thanks for taking Vulcan mainline.

Hi Amit,

Actually, this port was done over the week-end *without* access to Arcom/Eurotech's source code (the only thing I was able to download from the Eurotech web site is the board documentation). I'm usually extra careful when it comes to attributions...

Some of the settings have been reverse-engineered from the bootloader (the EXP_CS* timing section), and the rest is only based on the documentation. That's probably why there is no PC/104 support yet (still working on it). But honnestly, this is a classical IXP425 implementation, without anything fancy (much less effort than the PXA boards where source access was actually useful, and proper attribution was mentioned).

I can always add a "Based on Eurotech's documentation", if you want.

Cheers,

	M.

I'm the slime oozin' out from your TV set...

Hi Marc,

Sorry, I wasn't aware of that. If you did it independently, then I don't think attribution is required at all.

You are most welcome to borrow from the existing Vulcan port. If you would like to refer to it, please let me know. I will be glad to share the patches.

Thanks and regards,
- Amit
