There are two things that will help you straight away. The first is the
Linux Device Drivers book (version 2) - also available online for
The second is Documentation/pci.txt, and Documentation/DMA-mapping.txt

Another good bit of news is that providing the device follows standard
IDE bus mastering design (pretty much all do) then you only actually have
to write the tuning code for the chipset.
ide-pci.c contains a table of PCI capable devices and any driver needed.
You provide pci initialisers, dma finctions and ide functions.
Take a look at amd74xx.c for example - thats a driver letting ide-dma.c
do all the work.
