From b4dfbfa104b142b4e5585f33d03b22755704b1ff Mon Sep 17 00:00:00 2001 From: Fredrik Thulin Date: Sat, 9 Jul 2016 22:14:40 +0200 Subject: Clean up the CLI. A lot of the commands were just useful when testing/implementing features for the Alpha. Remove them now that they have been merged to projects/cli-test. --- projects/hsm/mgmt-dfu.c | 123 ------------------------------------------------ 1 file changed, 123 deletions(-) delete mode 100644 projects/hsm/mgmt-dfu.c (limited to 'projects/hsm/mgmt-dfu.c') diff --git a/projects/hsm/mgmt-dfu.c b/projects/hsm/mgmt-dfu.c deleted file mode 100644 index e57c521..0000000 --- a/projects/hsm/mgmt-dfu.c +++ /dev/null @@ -1,123 +0,0 @@ -/* - * mgmt-dfu.c - * --------- - * CLI code for looking at, jumping to or erasing the loaded firmware. - * - * Copyright (c) 2016, NORDUnet A/S All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are - * met: - * - Redistributions of source code must retain the above copyright notice, - * this list of conditions and the following disclaimer. - * - * - Redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution. - * - * - Neither the name of the NORDUnet nor the names of its contributors may - * be used to endorse or promote products derived from this software - * without specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS - * IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED - * TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A - * PARTICULAR PURPOSE ARE DISCLAIMED.
