+ Stuff for AMCC S5933 PCI Controller
+
+ Author: Michal Dobes <dobes@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.
