   I'd like to know what do you mean by "it" since it's certainly not in

   That looks like ""Intel PCI IDE Controller Specification".

   You probaly mean PC targeted controllers, since quite many non-PC chips do 
ignore that spec (IOC4, PowerMac, Toshiba SCC)... As for CS5520, what's the 
deviation here -- BMDMA regisrters at BAR2 only?
