From 870b8c04557f0b7441cc502debaf537984d77e2a Mon Sep 17 00:00:00 2001 From: Zachary T Welch Date: Tue, 17 Nov 2009 13:04:49 -0800 Subject: allow flash/nand banks commands to accept names Add get_flash_bank_by_name (and get_nand_device_by_name) helpers to retrieves struct flash_bank * (struct nand_device *) given a driver name and an (optional) driver-specific bank index. These are used to extend flash_command_get_bank_by_num (and nand_command_get_device_by_num) to allow all flash (nand) commands to reference defined banks by name, not just by number. To avoid some code duplication, add the flash/common.[ch] files to hold functionality common to both types driver. The first two methods are helpers for the above routines to find a bank specified by a "name" or "name.index" string. get_flash_name_index() finds the '.index' portion, while flash_driver_name_matches() performs the string portion matching. --- src/flash/common.h | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 src/flash/common.h (limited to 'src/flash/common.h') diff --git a/src/flash/common.h b/src/flash/common.h new file mode 100644 index 00000000..1fd0d774 --- /dev/null +++ b/src/flash/common.h @@ -0,0 +1,39 @@ +/*************************************************************************** + * Copyright (C) 2009 by 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.
