rapidio: fix use of non-compatible registers

2011-10-03T18:39:46+00:00

commit 284fb68d00c56e971ed01e0b4bac5ddd4d1b74ab upstream.

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 default routing initialization

2011-05-18T09:55:22+00:00

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.

RapidIO/mpc85xx: fix possible mport registration problems

2011-04-14T23:06:56+00:00

Fix a possible problem with mport registration left non-cleared after
fsl_rio_setup() exits on link error.  Abort mport initialization if
registration failed.

This patch is applicable to 2.6.39-rc1 only.  The problem does not exist
for earlier versions.

rapidio: remove mport resource reservation from common RIO code

2011-03-24T02:46:43+00:00

Removes resource reservation from the common sybsystem initialization code
and make it part of mport driver initialization.  This resolves conflict
with resource reservation by device specific mport drivers.

rapidio: modify mport ID assignment

2011-03-24T02:46:43+00:00

Changes mport ID and host destination ID assignment to implement unified
method common to all mport drivers.  Makes "riohdid=" kernel command line
parameter common for all architectures with support for more that one host
destination ID assignment.

Subsystem initialization sequence modified to support presence of multiple
RapidIO controllers in the system.  The new sequence is compatible with
initialization of PCI devices.
