Last change on this file since a902441a was a902441a, checked in by Joel Sherrill <joel.sherrill@…>, on 03/16/99 at 02:26:50

Patch from John S. Gwynne <jgwynne@…> to correct minor
problems that prevented the 19990302 snapshot from running on
the efi332.

I'm happy to report that rtems-19990302 is running on the efi332
board. I have enclosed a few minor patches below to the efi332 bsp. All
patches are within that library but one. make/custom/efi332.cfg has a
patch to select the right CPU_CFLAGS (at one time -m68332 was a
problem... -mcpu32 or -m68332 work fine now).
