Hi Guo,
Sorry for the late response.
Just as we discussed today, and also from the suggestions by Ray, in the new
patch I will
1. changed "UNIVERSAL_PAYLOAD_ DEBUG_PRINT_ERROR_LEVEL" to
"UEFI_PAYLOAD_DEBUG_PRINT_ERROR_LEVEL", and
2. add a comment referencing Debuglib.h to declare bits for "ErrorLevel"
parameters. The reason why better not just declare those common bits is because
it can cause confusion if other developers still use the rest.
What do you think?
Thanks,
Yuanhao

Subject: RE: [PATCH 1/2] UefiPayloadPkg: Add a new DebugPrintErrorLevelLib
instance
I replied in another email. It looks the comments are not addressed in this
patch, especially on this comment:
In the DebugPrintErrorLevel.h, ErrorLevel is defined as UINT32, but its usage
is not clear for bootloaders ( so need add more info in the header file)
Thanks,
Guo

Subject: [PATCH 1/2] UefiPayloadPkg: Add a new DebugPrintErrorLevelLib instance
It consumes the HOB defined in
UefiPayloadPkg/Include/Guid/DebugPrintErrorLevel.h, and allow bootloader to
config DebugPrintErrorLevel.
