All DFU related files have following headers: /* * g_dnl.c -- USB Downloader Gadget * * Copyright (C) 2012 Samsung Electronics * Lukasz Majewski <l.majew...@samsung.com> * * 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.

The code is "open", you can modify it and use with your product if you provide your's product source code when requested. > Because it has been merged into uboot library. > So, it could be used or released by every ARM SOC vendor?

This mean (with some simplification :-) ) that this vendor needs to publish source code for his product. > > Best wishes, > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > http://lists.denx.de/mailman/listinfo/u-boot -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
