2016-08-02rapidio: modify for rev.3 specification changesAlexandre Bounine1-35/+132
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.

2011-08-25rapidio: fix use of non-compatible registersAlexandre Bounine1-9/+9
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.
