PS27, Line 9: Use BHD instead of BDT as the name of cookie macro.
            : Use L2 to make it clear it is for level 2. The 'BHD2' is misleading,
            : which is going to be used for combo entry.
            : The definition in psp_verstage is also changed.
Please mark it up as a list, or do not wrap lines just because a sentence ends.
