The proposed patch failed some CI tests.
Details can be referred at: https://github.com/tianocore/edk2/pull/4866. Could you help to resolve them?
Please help to follow the step 11 in page: https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Development-Process and check the CI test results for the upcoming patch?
Best Regards,
Hao Wu

>
> TRB Template is 16 bytes. When boundary checking is 64 bytes for xHCI
> device/host memory address, it may exceed xHCI host memory pool and
> cause unwanted DXE_ASSERT. Introduce a new input parameter to indicate
> whether to enforce 64byte size alignment and round up. For TRB case,
> should set it to FALSE to skip the size round up.
