ARM: 7020/1: Check for multiple zreladdrs
Without CONFIG_AUTO_ZRELADDR being set the kernel needs a single zreladdr for building zImages. Bail out if we detect multiple zreladdrs without CONFIG_AUTO_ZRELADDR. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
