+ This function updates a form that has previously been registered with the HII
+ Database. This function will perform at most one update operation.
+
+ The form to update is specified by Handle, FormSetGuid, and FormId. Binary
+ comparisons of IFR opcodes are performed from the beginning of the form being
+ updated until an IFR opcode is found that exactly matches the first IFR opcode
+ specifed by StartOpCodeHandle. The following rules are used to determine if
+ an insert, replace, or delete operation is performed.
+
+ 1) If no matches are found, then NULL is returned.
+ 2) If a match is found, and EndOpCodeHandle is NULL, then all of the IFR opcodes
+ from StartOpcodeHandle except the first opcode are inserted immediately after
+ the matching IFR opcode in the form beng updated.
+ 3) If a match is found, and EndOpCodeHandle is not NULL, then a search is made
+ from the matching IFR opcode until an IFR opcode exatly matches the first
+ IFR opcode specified by EndOpCodeHandle. If no match is found for the first
+ IFR opcode specified by EndOpCodeHandle, then NULL is returned. If a match
+ is found, then all of the IFR opcodes between the start match and the end
+ match are deleted from the form being updated and all of the IFR opcodes
+ from StartOpcodeHandle except the first opcode are inserted immediately after
+ the matching start IFR opcode. If StartOpCcodeHandle only contains one
+ IFR instruction, then the result of ths operation will delete all of the IFR
+ opcodes between the start end matches.
+
+ If HiiHandle is NULL, then ASSERT().
+ If StartOpCodeHandle is NULL, then ASSERT().
+
+ @param[in] HiiHandle The HII Handle of the form to update.
+ @param[in] FormSetGuid The Formset GUID of the form to update. This
+ is an optional parameter that may be NULL.
+ If it is NULL, all FormSet will be updated.
+ @param[in] FormId The ID of the form to update.
+ @param[in] StartOpCodeHandle An OpCode Handle that contains the set of IFR
+ opcodes to be inserted or replaced in the form.
+ The first IFR instruction in StartOpCodeHandle
+ is used to find matching IFR opcode in the
+ form.
+ @param[in] EndOpCodeHandle An OpCcode Handle that contains the IFR opcode
+ that marks the end of a replace operation in
+ the form. This is an optional parameter that
+ may be NULL. If it is NULL, then an the IFR
+ opcodes specified by StartOpCodeHandle are
+ inserted into the form.
+
+ @retval EFI_OUT_OF_RESOURCES No enough memory resource is allocated.
+ @retval EFI_NOT_FOUND The following cases will return EFI_NOT_FOUND.
+ 1) The form specified by HiiHandle, FormSetGuid,
+ and FormId could not be found in the HII Database.
+ 2) No IFR opcodes in the target form match the first
+ IFR opcode in StartOpCodeHandle.
+ 3) EndOpCOde is not NULL, and no IFR opcodes in the
+ target form following a matching start opcode match
+ the first IFR opcode in EndOpCodeHandle.
+ @retval EFI_SUCCESS The matched form is updated by StartOpcode.
