- Stuff for AMCC S5933 PCI Controller
-
- Author: Michal Dobes <majkl@tesnet.cz>
-
- Inspirated from general-purpose AMCC S5933 PCI Matchmaker driver
- made by Andrea Cisternino <acister@pcape1.pi.infn.it>
- and as result of espionage from MITE code made by David A. Schleef.
- Thanks to AMCC for their on-line documentation and bus master DMA
- example.
