staging: fsl-mc: Changed version matching rules for MC object drivers

2015-04-03T11:55:03+00:00

Before this change, we were requiring a complete version match (major and
minor version numbers) between MC objects and corresponding drivers, to
allow MC objects to be bound to their drivers. We realized that a mismatch
in minor version numbers should be tolerated, as long as the major version
numbers match. This allows the driver to decide what to do in the minor
version mismatch case. For example, a driver may decide to run with
downgraded functionality if the MC firmware object has older minor version
number than the driver. Also, a driver with older minor version than the
MC firmware object may decide to run even though it cannot use newer
functionality of the MC object.

As part of this change, the dpmng Flib version was also updated
to match the latest MC firmware version.

staging: fsl-mc: Refactored fsl_mc_object_allocator driver init/exit

2015-04-03T11:55:03+00:00

 The fsl_mc_allocator driver does not need to be its own module
 as it is tightly integrated into the MC bus main driver. It is really
 just a sub-component of the MC bus driver. By not making fsl_mc_allocator
 its own module, we can have more control of when its initialization happens
 and we want it to happen before any driver that depends on the MC bus
 driver gets initialized.

staging: fsl-mc: Fix crash in fsl_mc_device_remove()

2015-04-03T11:55:03+00:00

Only call fsl_mc_io_destroy() if the DPRC being removed
actually had an mc_io object associated with. Child DPRCs
that have not been bound to the DPRC driver or the VFIO driver
will not have an mc_io associated with them.

staging: fsl-mc: Removed reordering of MC objects during bus scan

2015-04-03T11:55:03+00:00

MC objects discovered during an MC bus scan were being reordered
to ensure that all allocatable objects are probed before all
non-allocatable objects. However, this is not necessary, as
drivers of non-allocatable objects, that allocate allocatable
objects in their probe function, can return -EPROBE_DEFER
if such allocations fail.

staging: fsl-mc: Name MC object devices using decimal numbers

2015-04-03T11:55:03+00:00

MC object devices were being named using hexadecimaal numbers.
This was not consistent with the object naming conventions used
by MC DPLs and the MC restool.

staging: fsl-mc: fsl-mc object allocator driver

2015-03-07T01:29:10+00:00

The fsl-mc object allocator driver manages "allocatable" fsl-mc
objects such as DPBPs, DPMCPs and DPCONs. It provides services to
other fsl-mc drivers to allocate/deallocate these types of objects.

A DPRC (Data Path Resource Container) is an isolation device
that contains a set of DPAA networking devices to be
assigned to an isolation domain (e.g., a virtual machine).
