Users migrating Freescale's PowerPC SoC U-Boot code to their custom board, often overlook the need to execute set_liodns() and setup_portals() being called by platform files. So Move set_liodns() and setup_portals() to common u-boot boot sequence Signed-off-by: Prabhakar Kushwaha <prabhakar.kushwaha@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
