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.
