- Add an EDAC driver for the AMD VersalNET memory controller which
reports hw errors from different IP blocks in the fabric using an
IPC-type transport
- Drop the silly static number of memory controllers in the Intel EDAC
drivers (skx, i10nm) in favor of a flexible array so that former
doesn't need to be increased with every new generation which adds more
memory controllers; along with a proper refactoring
- Add support for two Alder Lake-S SOCs to ie31200_edac
- Add an EDAC driver for ADM Cortex A72 cores, and specifically for
reporting L1 and L2 cache errors
- Last but not least, the usual fixes, cleanups and improvements all
over the subsystem

Merge tag 'edac_updates_for_v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras
Pull EDAC updates from Borislav Petkov:
- Add support for new AMD family 0x1a models to amd64_edac
- Add an EDAC driver for the AMD VersalNET memory controller which
reports hw errors from different IP blocks in the fabric using an
IPC-type transport
- Drop the silly static number of memory controllers in the Intel EDAC
drivers (skx, i10nm) in favor of a flexible array so that former
doesn't need to be increased with every new generation which adds
more memory controllers; along with a proper refactoring

* tag 'edac_updates_for_v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: (23 commits)
EDAC/versalnet: Return the correct error in mc_probe()
EDAC/mc_sysfs: Increase legacy channel support to 16
EDAC/amd64: Add support for AMD family 1Ah-based newer models
EDAC: Add a driver for the AMD Versal NET DDR controller
dt-bindings: memory-controllers: Add support for Versal NET EDAC
RAS: Export log_non_standard_event() to drivers
cdx: Export Symbols for MCDI RPC and Initialization
cdx: Split mcdi.h and reorganize headers
EDAC/skx_common: Use topology_physical_package_id() instead of open coding
EDAC: Fix wrong executable file modes for C source files
EDAC/altera: Use dev_fwnode()
EDAC/skx_common: Remove unused *NUM*_IMC macros
EDAC/i10nm: Reallocate skx_dev list if preconfigured cnt != runtime cnt
EDAC/skx_common: Remove redundant upper bound check for res->imc
EDAC/skx_common: Make skx_dev->imc[] a flexible array
EDAC/skx_common: Swap memory controller index mapping
EDAC/skx_common: Move mc_mapping to be a field inside struct skx_imc
EDAC/{skx_common,skx}: Use configuration data, not global macros
EDAC/i10nm: Skip DIMM enumeration on a disabled memory controller
EDAC/ie31200: Add two more Intel Alder Lake-S SoCs for EDAC support
...
Move bitfield.h from the CDX controller directory to include/linux/cdx to make
them accessible to other drivers.
As part of this refactoring, split mcdi.h into two headers:
- mcdi.h: retains interface-level declarations
- mcdid.h: contains internal definitions and macros
This is in preparation for VersalNET EDAC driver that relies on it.

In cdx_rpmsg_probe(), strscpy() is incorrectly called with the length of
the source string (excluding the NUL terminator) rather than the size of
the destination buffer. This results in one character less being copied
from 'cdx_rpmsg_id_table[0].name' to 'chinfo.name'.
Use the destination buffer size instead to ensure the name is copied
correctly.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

RPMsg is used as a transport communication channel. This
change introduces RPMsg driver and integrates it with the
CDX controller.
