> macros
>
> ALIGNOF: Determining the alignment requirement of data types is crucial to
> ensure safe memory accesses when parsing untrusted data.
>
> IS_POW2: Determining whether a value is a power of two is important to
> verify whether untrusted values are valid alignment values.
>
> IS_ALIGNED: In combination with ALIGNOF data offsets can be verified.
> A more general version of IS_ALIGNED defined by several modules.
>
> ADDRESS_IS_ALIGNED: Variant of IS_ALIGNED for pointers and addresses.
> Replaces module-specific definitions throughout the codebase.
>
> ALIGN_VALUE_ADDEND: The added to align up can be used to directly
> determine the required offset for data alignment.

Suggest to break this into 2 patches:
The first one is for MdePkg for adding the macros. And the second one for
changes in MdeModulePkg.
For the MdeModulePkg changes, they look good to me:
Reviewed-by: Hao A Wu <hao.a...@intel.com>
You can add the above 'R-b' tag for your MdeModulePkg patch in the V2 series.
Best Regards,
Hao Wu
