uImages need a load address specified. This makes them incompatible with multiple zreladdrs. Catch this error before building an uImage so that we do not end up with broken uImages. The load address can still be specified with LOADADDR= on the command line. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
