From: Piotr Dymacz Date: Sat, 20 Aug 2016 22:32:13 +0000 (+0200) Subject: Include two trivial commands: button and sleep X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d57cd3a0bf2594a3de6646ba13e76d8b3aa26a99;p=oweals%2Fu-boot_mod.git Include two trivial commands: button and sleep These simple commands might be very useful in scripts and as we already using Hush shell type, it would be easier to transform recovery modes into some set of scripts instead of hard-coding them. --- diff --git a/u-boot/common/cmd_custom.c b/u-boot/common/cmd_custom.c index 94b7cbd..4e49479 100644 --- a/u-boot/common/cmd_custom.c +++ b/u-boot/common/cmd_custom.c @@ -1,22 +1,11 @@ /* - * (C) Copyright 2013 - * Piotr Dymacz (pepe2k), Real Time Systems, piotr@realtimesystems.pl, pepe2k@gmail.com - * Custom commands for U-Boot 1.1.4 modification. + * Copyright (C) 2016 Piotr Dymacz * - * See file CREDITS for list of people who contributed to U-Boot project. - * - * 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 3 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.
