+
+    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.
