From a7fd30c07fb9c2b7662ffaa48287b1997dc60796 Mon Sep 17 00:00:00 2001 From: Zachary T Welch Date: Fri, 4 Dec 2009 18:24:14 -0800 Subject: split NAND driver handling into nand/driver.[ch] This work parallels the NOR directory, encapsulating the NAND drivers into a separate file. This takes an extra step by encapsulating the type of data structure used to manage the drivers, allowing it to be changed from an array to a dynamic list in the future. --- src/flash/nand/driver.c | 79 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 src/flash/nand/driver.c (limited to 'src/flash/nand/driver.c') diff --git a/src/flash/nand/driver.c b/src/flash/nand/driver.c new file mode 100644 index 00000000..717f5aaa --- /dev/null +++ b/src/flash/nand/driver.c @@ -0,0 +1,79 @@ +/*************************************************************************** + * Copyright (C) 2005 by Dominic Rath * + * Copyright (C) 2007,2008 Øyvind Harboe * + * Copyright (C) 2008 by Spencer Oliver * + * Copyright (C) 2009 Zachary T Welch * + * * + * 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.
