For some use cases, Redfish host interface table relies on
the certain EFI protocols installation at the driver connection.
Redfish host interface DXE driver is not able to build the
SMBIOS type 42h record at driver entry point. This patch adds
the mechanism in Redfish host interface DXE driver to listen
to EFI protocol installed by platform library that indicates
the necessary information is ready for building SMBIOS 42h
record.

Hi Abner,
I found another bug as below.
+ if (Status == EFI_UNSUPPORTED || EFI_ALREADY_STARTED) {
+ Status = RedfishCreateSmbiosTable42 ();
Second condition check miss "Status ==" and RedfishCreateSmbiosTable42() is always called in driver entry.
Thanks,
Nickle

Subject: [EXTERNAL] [PATCH V2 1/2] RedfishPkg/RedfishHostInterface: Platform Redfish HI notification
**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**
From: Abner Chang <abner.chang@amd.com>
For some use cases, Redfish host interface table relies on the certain EFI protocols installation at the driver connection.
Redfish host interface DXE driver is not able to build the SMBIOS type 42h record at driver entry point. This patch adds the mechanism in Redfish host interface DXE driver to listen to EFI protocol installed by platform library that indicates the necessary information is ready for building SMBIOS 42h record.
