Ok, these warning/error lines are generated by this code: /* reset lp5523 led */ i2c_set_bus_num(1); state = 0xff; i2c_write(0x32, 0x3d, 1, &state, 1); i2c_set_bus_num(0); in function misc_init_r() in file board/nokia/rx51/rx51.c Above code worked fine in U-Boot 2013.04 and now in U-Boot from git master it generates warnings/errors.
