Last change on this file since 8ef3818 was 8ef3818, checked in by Joel Sherrill <joel.sherrill@…>, on Jun 12, 2000 at 7:57:02 PM

Patch from John Cotton <john.cotton@…>, Charles-Antoine Gauthier
<charles.gauthier@…>, and Darlene A. Stewart
<Darlene.Stewart@…> to add support for a number of very
significant things:

+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040

and PowerPC

+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use

same code base.

+ Rework of eth_comm BSP to utiltize above.

John reports this works on the 821 and 860

74#   rtems/c/src/lib/libcpu/m68k/m68040/fpsp
75# The default is to use the FPSP.
76# To use the msoft-float libraries, uncomment the three lines below.
