I am not the reviewer or maintainer of DynamicTablePkg, however this patch looks good.

> Subject: [edk2-devel] [PATCH v1 1/1] DynamicTablesPkg: Add SMBIOS String
> table helper library
> 
> [CAUTION: External Email]
> 
> The Section 6.1.3, SMBIOS specification version 3.6.0 describes the handling
> of test strings in SMBIOS tables.
> 
> Test strings are added at the end of the formatted portion of the SMBIOS
> structure and are referenced by index in the SMBIOS structure.
> 
> Therefore, introduce a SmbiosStringTableLib to simplify the publishing of the
> string set.
> 
> SmbiosStringTableLib introduces a concept of string table which records the
> references to the SMBIOS strings as they are added and returns an string
> reference which is then assigned to the string field in the formatted portion
> of the SMBIOS structure. Once all strings are added, the library provides an
> interface to get the required size for the string set. This allows sufficient
> memory to be allocated for the SMBIOS table.
> The library also provides an interface to publish the string set in accordance
> with the SMBIOS specification.
> 
> Example:
> EFI_STATUS
> BuildSmbiosType17Table () {
>   STRING_TABLE         StrTable;
>   UINT8                DevLocatorRef;
>   UINT8                BankLocatorRef;
>   SMBIOS_TABLE_TYPE17  *SmbiosRecord;
>   CHAR8                *StringSet;
>   ...
> 
>   // Initialize string table for 7 strings
>   StringTableInitialize (&StrTable, 7);
> 
>   StringTableAddString (&StrTable, "SIMM 3", &DevLocatorRef);
>   StringTableAddString (&StrTable, "Bank 0", &BankLocatorRef);
>   ...
> 
>   SmbiosRecord = AllocateZeroPool (
>                    sizeof (SMBIOS_TABLE_TYPE17) +
>                      StringTableGetStringSetSize (&StrTable)
>                    );
>   ...
>   SmbiosRecord->DeviceLocator = DevLocatorRef;
>   SmbiosRecord->BankLocator = BankLocatorRef;
>   ...
>   // get the string set area
>   StringSet = (CHAR8*)(SmbiosRecord + 1);
> 
>   // publish the string set
>   StringTablePublishStringSet (
>     &StrTable,
>     StringSet,
>     StringTableGetStringSetSize (&StrTable)
>     );
>
