This file setups UART5 based serial to be used as pre-relocation console in the U-Boot proper. On purpose pinux configuration is omitted here as it has been already done in SPL. For early pre-relocation code we only need the serial device from DTS. Signed-off-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Peng Fan <peng.fan@nxp.com>
