Description
After playing around with Haiku's ATA stack I implemented a basic driver to support Highpoint HPT36x/37x devices. This enables my test system to boot up correctly and use the drives attached to this controller. As with all Haiku ATA drivers (as far as I understand the code) there is no way of setting DMA mode by the driver. ATA stack relies on correct initialisation of controller/drives by BIOS.

just create a folder 'highpoint_ide_pci' in add-ons/kernel/busses/ata Copy highpoint* files and first Jamfile in new folder copy Jamfile.2 as Jamfile in ata folder (replace existing)
Don't forget to include highpoint_ide_pci in build setup, so that the driver is added to the images.

Can you submit a Git patch instead? You can do that by committing your changes/additions, then running git format-patch -1 to get an exported patch file.

It looks like the name/email in there is bogus ... is that what you wanted? Or did you forget to git config --global user.name/user.email?

Hmm. Strange. I thought I did that?! I replaced the file, please check again.

Applied (with some coding style fixes) in hrev51646. Thanks!

Why does this need to be a separate driver and can't be part of the generic IDE one? Also, waddlesplash, you let some styleguide violations get through (80 columns limit, at least).

I don't know what the design goal/philosophy was behind the ATA stack or the generic driver, but there are also different separate drivers for other controllers as well. And putting some PCI device specific code into something what calls itself "generic" somehow defeats it's purpose, doesn't it? Also if you look at #13620 you see that the generic driver does not behave very well if it needs to attach to 2 different PCI devices, so I created it as separate driver.
