[edk2-devel] [PATCH v2 1/1] UefiPayloadPkg: Remove x86 legacy UART defaults

[Ma, Maurice]

As I mentioned in the previous comments,  could you please CC all UefiPayloadPkg maintainers listed in the Maintainers.txt under the root of the EDK2 directory for code changes in UefiPayloadPkg  ?  

Other than that, this patch looks good to me.

Thanks
