From 0a823aa2a8a8c0685e73900f387d602d7edafc0e Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Wed, 9 Jul 2008 22:30:30 +0800 Subject: Add 'license' command to U-Boot command line The 'license' command includes the U-Boot license (GPLv2) into the actual bootloader binary. The license text can be shown interactively at the U-Boot commandline. For products where the commandline can actually be accessed by the end user, this helps to prevent inadvertent GPL violations, since the GPLv2 license text can no longer be 'forgotten' to be included into the product. The 'license' command can be enabled by CONFIG_CMD_LICENSE.
