From 865efd828a267992db0f2a92a731c5ce23a34236 Mon Sep 17 00:00:00 2001 From: Zachary T Welch Date: Wed, 2 Dec 2009 17:18:05 -0800 Subject: move jtag drivers to src/jtag/drivers Moves JTAG interface drivers to src/jtag/drivers/, Adds src/jtag/drivers/Makefile.am. Builds libocdjtagdrivers.la. Flattens the rlink driver files into the drivers/ directory, adding the 'rlink_' prefix or '.rlink' suffix as appropriate. --- src/jtag/parport.c | 533 ----------------------------------------------------- 1 file changed, 533 deletions(-) delete mode 100644 src/jtag/parport.c (limited to 'src/jtag/parport.c') diff --git a/src/jtag/parport.c b/src/jtag/parport.c deleted file mode 100644 index e5f56113..00000000 --- a/src/jtag/parport.c +++ /dev/null @@ -1,533 +0,0 @@ -/*************************************************************************** - * Copyright (C) 2005 by Dominic Rath * - * Dominic.Rath@gmx.de * - * * - * Copyright (C) 2008 by Spencer Oliver * - * spen@spen-soft.co.uk * - * * - * This program is free software; you can redistribute it and/or modify * - * it under the terms of the GNU General Public License as published by * - * the Free Software Foundation; either version 2 of the License, or * - * (at your option) any later version. * - * * - * This program is distributed in the hope that it will be useful, * - * but WITHOUT ANY WARRANTY; without even the implied warranty of * - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
