Add a NXP specific hook to preserve SMMU mappings present at
boot time (created by the boot loader). These are needed for
MC firmware present on some NXP chips to continue working
across kernel boot and SMMU initialization.

On some platforms, the firmware will setup hardware to read from a given

scanning out a splash screen from physical memory.
During Linux' boot process, the ARM SMMU will configure all contexts to

the reserved regions associated with them. This happens before the SMMU

through the MAC device which makes no sense because it's neither dma-able

This patch series contains several fixes in preparation for SMMU
support on NXP LS1043A and LS1046A chips. Once these get picked up,
I'll submit the actual SMMU enablement patches consisting in the
required device tree changes.

Add an API that retrieves the 'struct device' that the specified fman
port probed against. The new API will be used in a subsequent iommu
enablement related patch.

Enabling SMMU altered the order of device probing causing the dpaa1
ethernet driver to get probed before qbman and causing a boot crash.

The driver relies on the no longer valid assumption that dma addresses

liodn base registers are specific to PAMU based NXP systems and on SMMU
based ones are reserved. Don't access them if PAMU is compiled in.

The dma transactions initiator is the rx fman port so that's the device
that the dma mappings should be done. Previously the mappings were done
through the MAC device which makes no sense because it's neither dma-able
nor connected in any way to smmu.

During probing, FMAN is reset thus losing all its register
settings. Backup port ICID registers before reset and restore
them after, similarly to how it's done on powerpc / PAMU based
platforms.
This also has the side effect of disabling the old code path

Fix issue with the entry indexing in the sg frame cleanup code being
off-by-1. This problem showed up when doing some basic iperf tests and
manifested in traffic coming to a halt.

Add a couple of new APIs to check the probing status of the required
cpu bound qman and bman portals:
'int bman_portals_probed()' and 'int qman_portals_probed()'.
They return the following values.
* 1 if qman/bman portals were all probed correctly
* 0 if qman/bman
From: Laurentiu Tudor
ARM SoCs use SMMU so the liodn fixup done in the qman driver is no
longer making sense and it also breaks the ICID settings inherited
from u-boot. Do the fixups only for PPC targets.
