This patch series adds HMAT tables for Arm's Neoverse reference design
multi-chip platforms. The first patch in the series adds helper macros to create
HMAT table within SgiPkg and the rest two patches adds HMAT table for
RD-N1-Edge-X2 and RD-V1-MC platforms respectively.

Latency and Bandwidth Information, Memory Side Cache Information
structures in the HMAT table.

Hi,
Now either you have a very odd machine in which latencies are round numbers that happen
to look like the values in SLIT or ... ?
HMAT has very carefully defined real world units to overcome the fact that there
was no standard scaling etc for SLIT. It is not a good idea to put tables out
there which don't do this right as someone may copy this for a real system
and we end up with HMAT being roughly as useless for performance prediction as
SLIT is. That is not something I would want to see.

This patch is for a platform that is modelled and not for an actual board. So
the latencies are hypothetical but ensure that the typical latency between two
chips is represented. These tables are not expected to be copied for another
platform without understanding what these values mean. Such a copy, without
understanding what is being copied, would be an error in judgement on the part
of the person doing it. The commit message of this patch (in v2) can be updated
to exercise caution on reusing these values.

No one reads commit messages. So if you want to avoid people copying them put a
comment in the actual file. Or just make up some more plausible numbers :)
All we really need here is to avoid giving the impression that copying numbers from
SLIT is valid.
