EDAC/r82600: Remove this obsolete driver

This driver supports the Radisys 82600 embedded chipset, which was used with
Pentium III-era CPUs. It is highly unlikely that it is still used. Besides
its own documentation, the only information I was able to find about the
R82600, after looking through many pages of Google results, was that it was
used in a Nokia 2G GSM base station.

The original author said:

"This was after Bluesmoke (watch was out-of-tree), and was pay of the first
set of in tree edac drivers (a fresh design as far as I remember).

This particular driver did apparently get used by Akamai quite heavily and
widely  but all ancient history now. The Radisys r82600 edac driver 
r82600_edac.c was closely related hardware from the same era, and can probably
go too (although being embedded hardware, it's possible its production
lifespan was considerably longer).

Tim."

EDAC/i82443bxgx: Remove driver that has been marked broken since 2007

The history of this driver is pretty amusing. It was marked broken in
2007 in

28f96eeafc89 ("drivers/edac-new-i82443bxgz-mc-driver: mark as broken").

It was then fixed in 2008 in

53a2fe5804e8 ("edac: make i82443bxgx_edac coexist with intel_agp"),

but the dependency on BROKEN was never removed. Given that this was never
fixed in the last ~18 years, it is obvious there is no demand for this driver.
Remove it and move the former maintainer to the CREDITS file.

EDAC/{skx_common,imh}: Add EDAC driver for Intel Diamond Rapids servers

Intel Diamond Rapids CPUs include Integrated Memory and I/O Hubs (IMH).
The memory controllers within the IMHs provide memory stacks to the
processor. Create a new driver for this IMH-based memory controllers
rather than applying additional patches to the existing i10nm_edac.c
for the following reasons:

1) The memory controllers are not presented as PCI devices; instead,
the detection and all their registers have been transitioned to
MMIO-based memory spaces.

2) Validation processes are costly. Modifications to i10nm_edac would
require extensive validation checks against multiple platforms,
including Ice Lake, Sapphire Rapids, Emerald Rapids, Granite Rapids,
Sierra Forest, and Grand Ridge.

3) Future Intel CPUs will likely only need patches on top of this new
EDAC driver. Validation can be limited to Diamond Rapids servers
and future Intel CPU generations.

EDAC: Add a driver for the AMD Versal NET DDR controller

Add a driver for the AMD Versal NET DDR memory controller which supports
single bit error correction, double bit error detection and other system
errors from various IP subsystems (e.g., RPU, NOCs, HNICX, PL).

The driver listens for notifications from the NMC (Network management
controller) using RPMsg (Remote Processor Messaging).

The channel used for communicating to RPMsg is named "error_edac". Upon
receipt of a notification, the driver sends a RAS event trace.

EDAC: Add EDAC driver for ARM Cortex A72 cores

The driver is designed to support error detection and reporting for
Cortex A72 cores, specifically within their L1 and L2 cache systems.
The errors are detected by reading CPU/L2 memory error syndrome
registers.

Unfortunately there is no robust way to inject errors into the caches,
so this driver doesn't contain any code to actually test it. It has
been tested though with code taken from an older version [1] of this
driver. For reasons stated in thread [1], the error injection code is
not suitable for mainline, so it is removed from the driver.
