Hi Liming,

> What’s your comments for this patch?
The patch was reviewed by Pierre at https://edk2.groups.io/g/devel/message/118589 before the feature freeze email was sent out.
Pierre had some minor recommendations that Abdul has addressed in the V2 patch. Ideally Pierre’s the r-b tag could have been carried forward.

> Is this a required bug fix or new feature?
This is adding a new feature by introducing a new API, and I think it should not impact the existing functionality as such.
So, by merging this patch the risk of breaking existing functionality seems to be low.

This patch looks good to me.

[AMD Official Use Only - General]

Hi Liming,
    This patch provides an API to add integer value to AML package node.
Using this API user can create CXL device with two PNPID.
Without this API user has to rely on static ASL files.

This patch is required for platform who uses DynamicTablesPkg to generate ACPI tables based on this stable release.

Thanks
AbduL
