rapidio: modify for rev.3 specification changes

2016-08-02T23:35:37+00:00

Implement changes made in RapidIO specification rev.3 to LP-Serial Physical Layer register definitions: - use per-port register offset calculations based on LP-Serial Extended Features Block (EFB) Register Map type (I or II) with different per-port offset step (0x20 vs 0x40 respectfully). - remove deprecated Parallel Physical layer definitions and related code.

rapidio: fix use of non-compatible registers

2011-08-25T23:25:34+00:00

Replace/remove use of RIO v.1.2 registers/bits that are not forward-compatible with newer versions of RapidIO specification. RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR, Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR. Use of removed (since RIO v.1.3) register bits affects users of currently available 1.3 and 2.x compliant devices who may use not so recent kernel versions. Removing checks for unsupported bits makes corresponding routines compatible with all versions of RapidIO specification. Therefore, backporting makes stable kernel versions compliant with RIO v.1.3 and later as well.

rapidio: fix IDLE2 bits corruption

2010-10-28T01:03:16+00:00

RapidIO spec v.2.1 adds Idle Sequence 2 into LP-Serial Physical Layer. The fix ensures that corresponding bits are not corrupted during error handling.

rapidio: use stored ingress port number instead of register read

2010-10-28T01:03:15+00:00

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