From 90014dc218ec671a7ea66ac1f927d2324e84b17d Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 16 Sep 2008 19:03:51 +0000 Subject: 2008-09-16 Joel Sherrill * shared/m68kbspgetworkarea.c: Add use of bsp_get_work_area() in its own file and rely on BSP Framework to perform more initialization. Remove unnecessary includes of rtems/libio.h and rtems/libcsupport.h. * shared/m68kpretaskinghook.c: Removed. --- c/src/lib/libbsp/m68k/shared/m68kpretaskinghook.c | 66 ----------------------- 1 file changed, 66 deletions(-) delete mode 100644 c/src/lib/libbsp/m68k/shared/m68kpretaskinghook.c (limited to 'c/src/lib/libbsp/m68k/shared/m68kpretaskinghook.c') diff --git a/c/src/lib/libbsp/m68k/shared/m68kpretaskinghook.c b/c/src/lib/libbsp/m68k/shared/m68kpretaskinghook.c deleted file mode 100644 index 20865bfff0..0000000000 --- a/c/src/lib/libbsp/m68k/shared/m68kpretaskinghook.c +++ /dev/null @@ -1,66 +0,0 @@ -/* - * This routine is an implementation of the bsp_pretasking_hook - * that can be used by all m68k BSPs following linkcmds conventions - * regarding heap, stack, and workspace allocation. - * - * COPYRIGHT (c) 1989-1999. - * On-Line Applications Research Corporation (OAR). - * - * The license and distribution terms for this file may be - * found in the file LICENSE in this distribution or at - * http://www.rtems.com/license/LICENSE. - * - * $Id$ - */ - -#include -#include -#include - -/* - * Function: bsp_pretasking_hook - * Created: 95/03/10 - * - * Description: - * BSP pretasking hook.
