From 8ef38186faea3d9b5e6f0f1242f668cb7e7a3d52 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Mon, 12 Jun 2000 19:57:02 +0000 Subject: Patch from John Cotton , Charles-Antoine Gauthier , and Darlene A. 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.
