The current brcmstb driver works for Arm and Arm64. A few things are
modified here for us to support MIPs as well.
o There are four outbound range register groups and each directs a window
of up to 128MB. Even though there are four 128MB DT "ranges" in the
bmips PCIe DT node, these ranges are contiguous and are collapsed into
a single range by the OF range parser. Now the driver assumes a single
range -- for MIPs only -- and splits it back into 128MB sizes.
o For bcm7425, the config space accesses must be 32-bit reads or
writes. In addition, the 4k config space register array is missing
and not used.
o The registers for the upper 32-bits of the outbound window address do
not exist.
o Burst size must be set to 256 (this refers to an internal bus).

Get "syscon" pcie_mode and pcie_id offset from the argument of
"ti,syscon-pcie-id" and "ti,syscon-pcie-mode" phandle respectively.
Previously a subnode to "syscon" node was added which has the
exact memory mapped address of pcie_mode and pcie_id but now the
offset of pcie_mode and pcie_id within "syscon" is now being passed
as argument to "ti,syscon-pcie-id" and "ti,syscon-pcie-mode" phandle.
If the offset is not provided in "ti,syscon-pcie-id"/"ti,syscon-pcie-mode",

When Samsung PCIe Gen4 NVMe is connected to Intel ADL VMD, the
combination causes AER message flood and drags the system performance
down.
The issue doesn't happen when VMD mode is disabled in BIOS, since AER
isn't enabled by acpi_pci_root_create() . When VMD mode is enabled, AER
is enabled regardless of _OSC:
[ 0.410076] acpi PNP0A08:00: _OSC: platform does not support [AER]
...
[ 1.486704] pcieport 10000:e0:06.0: AER: enabled with IRQ 146
Since VMD is an aperture to regular PCIe root ports, honor ACPI _OSC to
disable PCIe features accordingly to resolve the issue.

It looks like that mvebu PCIe controller has for each PCIe link fully
independent PCIe host bridge and so every PCIe Root Port is isolated not
only on its own bus but also isolated from each others. But in past device
tree structure was defined to put all PCIe Root Ports (as PCI Bridge
devices) into one root bus 0 and this bus is emulated by pci-mvebu.c
driver.
Probably reason for this decision was incorrect understanding of PCIe
topology of these Armada SoCs and also reason of misunderstanding how is
PCIe controller generating Type 0 and Type 1 config requests (it is fully
different compared to other drivers). Probably incorrect setup leaded to
very surprised things like having PCIe Root Port (PCI Bridge device, with
even incorrect Device Class set to Memory Controller) and the PCIe device
behind the Root Port on the same PCI bus, which obviously was needed to
somehow hack (as these two devices cannot be in reality on the same bus).
Properly set mvebu local bus number and mvebu local device number based on
PCI Bridge secondary bus number configuration. Also correctly report
configured secondary bus number in config space. And explain in driver
comment why this setup is correct.

The struct cdns_pcie already contains the struct device for the j721e PCIe
controller. There's no need to store another copy in struct j721e_pcie.
Remove the redundant copy from struct j721e_pcie.

of_device_get_match_data() returns "void *", so no cast is needed when
assigning the result to a pointer type. Drop the unnecessary cast.

The kirin driver only needs the device data, not the whole struct
of_device_id. Use of_device_get_match_data() instead of of_match_device().
No functional change intended.
