This modification is part of the submitted modifications necessary to support the IBM PPC405 family. This submission was reviewed by Thomas Doerfler <Thomas.Doerfler@imd-systems.de> who ensured it did not negatively impact the ppc403 BSPs. The submission and tracking process was captured as PR50. * custom/gen405.cfg: New file. * custom/helas403.cfg: Modified to generate Srecords.
