2011-05-18rapidio: fix default routing initializationAlexandre Bounine3-0/+21
Fix switch initialization to ensure that all switches have default routing disabled. This guarantees that no unexpected RapidIO packets arrive to the default port set by reset and there is no default routing destination until it is properly configured by software. This update also unifies handling of unmapped destinations by tsi57x, IDT Gen1 and IDT Gen2 switches.

2011-01-13rapidio: use common destid storage for endpoints and switchesAlexandre Bounine4-107/+61
Change code to use one storage location common for switches and endpoints. This eliminates unnecessary device type checks during basic access operations. Logic that assigns destid to RIO devices stays unchanged - as before, switches use an associated destid because they do not have their own.

2010-10-27rapidio: fix destructive port EM initialization for Tsi568Alexandre Bounine1-5/+10
Replace possibly damaging broadcast writes into the per-port SP_MODE registers with individual writes for each port. This will preserve individual port configurations in case if ports are configured differently.
