The rename from i2cexio to i2cexio0 is in preparation for adding
i2cexio1 which will use the demuxer for IIC1/I2C1.
The reindexing from i2c8 to i2c10 is to allow space for grouping of
additional GPIO buses to be added by follow-up patches to support demuxing
of other i2c buses.
Also note that fallback to GPIO is not provided by the hardware for IIC0/I2C0.

Identify the SoC type and revision, and register this information with
the SoC bus, so it is available under /sys/devices/soc0/, and can be
checked where needed using soc_device_match().
Identification is done using the Product Register or Common Chip Code
Register, as declared in DT (PRR only for now), or using a hardcoded
fallback if missing.
Example:
Detected Renesas R-Car Gen2 r8a7791 ES1.0
...
# cat /sys/devices/soc0/{machine,family,soc_id,revision}
Koelsch
R-Car Gen2
r8a7791

The flush_cache_range() function (similarly for flush_cache_page()) is
called when the kernel is changing an existing VA->PA mapping range to
either a new PA or to different attributes. Since ARMv8 has PIPT-like
D-caches, this function does not need to perform any D-cache
maintenance. The I-cache maintenance is already handled via set_pte_at()
and flush_cache_range() cannot anyway guarantee that there are no cache
lines left after invalidation due to the speculative loads.
This patch makes flush_cache_range() a no-op.

Because host controller has the CDETECT register through SDx_CDN line.

Following the Amlogic Linux kernel, it seem the only differences
between the GXL and GXM SoCs are the CPU Clusters.
This commit renames the gxl-s905d-p23x DTSI in a common file for
S905D p23x and S912 q20x boards.
Then adds a meson-gxm dtsi and reproduce the P23x to Q20x boards
dts files since the S905D and S912 SoCs shares the same pinout
and the P23x and Q20x boards are identical.

Intel Xeons from Ivy Bridge onwards support a processor identification
number set in the factory. To the user this is a handy unique number to
identify a particular CPU. Intel can decode this to the fab/production
run to track errors. On systems that have it, include it in the machine
check record. I'm told that this would be helpful for users that run
large data centers with multi-socket servers to keep track of which CPUs
are seeing errors.
Boris:
* Add some clarifying comments and spacing.
* Mask out [63:2] in the disabled-but-not-locked case
* Call the MSR variable "val" for more readability.
