This modification is part of the submitted modifications necessary to
support the IBM PPC405 family. This submission was reviewed by
Thomas Doerfler <Thomas.Doerfler@…> 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.
  • Property mode set to 100644
