From 3ab61f0a35a49fa26dde66047235935094582dd3 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Mon, 12 Jun 2000 21:34:51 +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. John reports this works on the 821 and 860. --- c/src/lib/libbsp/m68k/mvme167/startup/elflinkcmds | 214 ---------------------- 1 file changed, 214 deletions(-) delete mode 100644 c/src/lib/libbsp/m68k/mvme167/startup/elflinkcmds (limited to 'c/src/lib/libbsp/m68k') diff --git a/c/src/lib/libbsp/m68k/mvme167/startup/elflinkcmds b/c/src/lib/libbsp/m68k/mvme167/startup/elflinkcmds deleted file mode 100644 index 3aa5a9d279..0000000000 --- a/c/src/lib/libbsp/m68k/mvme167/startup/elflinkcmds +++ /dev/null @@ -1,214 +0,0 @@ -/* - * This file contains directives for the GNU linker which are specific - * to the Motorola MVME167 board.
