They are required to be updated. 3) For the change in MdePkg\Library\BasePciExpressLib, why remove ASSERT() in PciExpressRegisterForRuntimeAccess() function? 4) For the change in MdePkg\Library\BasePciExpressLib, PcdPciExpressBaseSize() function header return value description is incorrect. 5) For the change in MdePkg\Library\BasePciExpressLib, PciExpressAndThenOr32() function should return UINT32, but the code uses return (UINT16) ~0;. There are similar issues in other function implementation. Please check them.
