Thanks for the updating. These changes make sense.
Reviewed-by: Dandan Bi <dandan.bi@intel.com>  for this patch series.

But the Spec seems not to be clear enough.
When looking into details about the "progress" parameter in EFI HII Configuration Routing Protocol and  EFI_HII_CONFIG_ACCESS_PROTOCOL.

Description of "progress" parameter in ExtractConfig() in UEFI 2.7 Spec:
Progress
On return, points to a character in the Request string. Points to the string's null terminator if request was successful. Points to the most recent '&' before the first failing name / value pair (or the beginning of the string if the failure is in the first name / value pair) if the request was not successful

EFI_NOT_FOUND
A configuration element matching the routing data is not found. Progress set to the first character in the routing header.


Description of "progress" parameter in RouteConfig () in UEFI 2.7 Spec:
Progress
a pointer to a string filled in with the offset of the most recent '&' before the first failing name / value pair (or the beginning of the string if the failure is in the first name / value pair) or the terminating NULL if all was successful.

EFI_NOT_FOUND
Target for the specified routing data was not found.

Compared with ExtractConfig(), the description of "Progress" parameter in RouteConfig()  is not very clear. 
We think an ECR is nice to have to clarify them. What do you think?


Thanks,
Dandan

Subject: [edk2] [PATCH 1/8] IntelFrameworkModulePkg/LegacyBootMaintUiLib: Update RouteConfig function

According to UEFI spec, the RouteConfig protocol function should populate the Progress pointer with an address inside Configuration.  This patch ensures that these functions are compliant when EFI_NOT_FOUND is returned.
