Lv Ruyi d37b07897e memory: fsl-corenet-cf: Use helper function devm_platform_ioremap_resource()
Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately.Make the
code simpler without functional changes.

Qiheng Lin b11a188aef memory: fsl-corenet-cf: Remove redundant dev_err call in ccf_probe()
There is a error message within devm_ioremap_resource already, so remove
the dev_err call to avoid redundant error message.

Krzysztof Kozlowski dd85345abc memory: fsl-corenet-cf: Fix handling of platform_get_irq() error
platform_get_irq() returns -ERRNO on error.  In such case comparison
to 0 would pass the check.

Luis de Bethencourt 613a91e275 memory: fsl-corenet: Fix module autoload for OF platform driver
This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.

Scott Wood c3e09b3a90 memory/fsl-corenet-cf: Add t1040 support
T1040 has a different version of corenet-cf, despite being incorrectly
labelled with a fsl,corenet2-cf compatible.  The t1040 version of
corenet-cf has a version register that can be read to distinguish.  The
t4240/b4860 version officially does not, but testing shows that it does
and has a different value, so use that.  If somehow this ends up not
being reliable and we treat a t4240/b4860 as a t1040 (the reverse
should not happen, as t1040's version register is official), currently
the worst that should happen is writing to reserved bits to enable
events that don't exist.

The changes to the t1040 version of corenet-cf that this driver cares
about are the addition of two new error events.  There are also changes
to the format of cecar2, which is printed, but not interpreted, by this
driver.

Wolfram Sang 0f0d7e7b02 memory: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Scott Wood 54afbec0d5 memory: Freescale CoreNet Coherency Fabric error reporting driver
The CoreNet Coherency Fabric is part of the memory subsystem on
some Freescale QorIQ chips.  It can report coherency violations (e.g.
due to misusing memory that is mapped noncoherent) as well as
transactions that do not hit any local access window, or which hit a
local access window with an invalid target ID.
