[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

DynamicTablesPkg: Adds integer to the AML package node
[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
