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. Signed-off-by: Harald Welte <laforge@openmoko.org>
