For GICD and GICR a SOC needs to implement 2 callbacks to get the base
of those interrupt controllers.
For all the cpu GIC the code loops over all the DEVICE_PATH_GICC_V3
devices in a similar fashion to how x86 lapics are added. It's up to the
SOC to add those devices to the tree.

In soundwire.h, SOUNDWIRE_DPN MIN & MAX are set to 1 and 14. When
creating the dpn array, the length was set to MAX - MIN or 13, numbered
0 to 12.
When accessing the array, the code was bailing out if a value greater
than MAX was trying to be accessed, so the array was able to be overrun
by two structure lengths.
Fix this problem by:
1) Not subtracting the MIN value when creating the array, which does
waste a little space. If anyone wants to refactor the code to fix that,
please feel free.
2) Breaking out of the loop when the port is equal to the MAX port
number instead of just when it's greater than the max port number.

Registering Clock Driver (RCD) is responsible for driving address and
control nets on RDIMM and LRDIMM applications. Its operation is
configurable by a set of Register Control Words (RCWs). There are two
ways of accessing RCWs: in-band on the memory channel as MRS commands
("MR7") or through I2C.
Access through I2C is generic, while MRS commands are passed to memory
controller registers in an implementation-specific way.
See JESD82-31 JEDEC standard for full details.

CXL (Compute Express Link) [1] is a cache-coherent interconnect
standard for processors, memory expansion and accelerators.
CXL memory is provided through CXL device which is connected
through CXL/PCIe link, while regular system memory is provided
through DIMMs plugged into DIMM slots which are connected to
memory controllers of processor.
With CXL memory, the server's memory capacity is increased.
CXL memory is in its own NUMA domain, with longer latency
and added bandwidth, comparing to regular system memory.
Host firmware may present CXL memory as specific purpose memory.
Linux kernel dax driver provides direct access to such differentiated
memory. In particular, hmem dax driver provides direct access to
specific purpose memory.
Specific purpose memory needs to be represented in e820 table as
soft reserved, as described in [2].
Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory)
resource that needs to be soft reserved.
Add soft_reserved_ram_resource macro to allow soc/mb code to add

This patch provides helper functions to read or write a register via the
MDIO bus. They can be used from drivers to easily access registers on
the MDIO bus.

This patch extends the available device paths with a new device 'mdio'.
MDIO is the 'Management Data Input/Output' called interface which is
used to access an Ethernet PHY behind a MAC to change settings. The real
payload data path is not handled by this interface.
To address the PHY correctly on the MDIO bus, there is a 5 bit address
needed, which often can be configured via pins on the mainboard.
Therefore, the new introduced device has an 'addr' field to define its
address. If one wants to use a MDIO device in devicetree, the syntax is
straight forward (example):
device mdio 0x2 on end
As the MDIO interface is driven by the MAC, most likely this MDIO device
will be hooked in as a child device of the (PCI attached) MAC device.
With the new introduced ops_mdio a new interface is added to provide an
API for read and write access over MDIO.

Add pcie_find_dsn() to detect and match PCIe device serial
number. In addition, vendor ID is matched when provided.
