the PW message. If source RIO device is not available (power down or RIO link
failure) trace back to a last available switch/port on the PW message route
and service failure at that point.

A switch port information is obtained and stored during RIO device setup.
Therefore repeated reads from Switch Port Information CAR may be removed.

Create back and forward links between RIO devices. These links are intended for
use by error management and hot-plug extensions. Links for redundant RIO
connections between switches are not set (will be fixed in a separate patch).

2. Enumerator sets Component Tag (!= 0) immediately during device setup.
This allows to identify the device if the redundant route exists in a RIO
system.

This set of RapidIO patches adds support for new IDT Gen2 sRIO switch
devices - CPS-1848 and CPS-1616.
Adding these sRIO switches required to implement standard error recovery
mechanism defined by the RapidIO specification.

A switch ingress port number has to be saved for software assisted error

to remove several register reads from the RIO enumeration process.
