Last change on this file since f50952c was f50952c, checked in by Joel Sherrill <joel.sherrill@…>, on 04/07/00 at 19:04:12

Patch from Charles-Antoine Gauthier <charles.gauthier@…> after
feedback from Eric Norum <eric@…> on static and
dynamic RAM sizing issues while still having as much shared
code as possible across the m68k BSPs.
