Hi Michael,
Please see my response inline marked [SAMI].
Other than the minor space change needed to match the coding style, this patch looks good to me.
With that changed:

Subject: [PATCH v1 1/1] StandaloneMmPkg/StandaloneMmCore: Fix compiler warning
From: Michael Kubacki <michael.kubacki at microsoft.com>
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3204
Fixes the following compiler warning in VS2019 by changing defining
the MmramRangeCount variable to be UINTN and type casting prior
to value assignment.
\edk2\StandaloneMmPkg\Core\StandaloneMmCore.c(570): error C2220:
the following warning is treated as an error
\edk2\StandaloneMmPkg\Core\StandaloneMmCore.c(570): warning C4244:
'=': conversion from 'UINT64' to 'UINT32', possible loss of data

[SAMI] There should be no space between the typecast and the variable, i.e. space after typecast (UINTN) and MmramRangesHobData.
Same at other places in this file.
