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.

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).

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

Add check for access to port-write (PW) message source device before processing
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.

Add explicit device access check before performing device enumeration.
This gives a chance to clear possible link error conditions by issuing safe
maintenance read request(s).

This set of RapidIO patches extends support for standard error recovery
mechanism and adds new IDT Gen2 sRIO switch devices - CPS-1848 and CPS-1616.
Implementation of the standard error-stopped state recovery mechanism (as
defined by the RapidIO specification) is required for the new switches.
The
Add the RIO switch driver and definitions for IDT CPS-1848 and CPS-1616 Gen2
devices.
