Of course, it's what you told Uboot to do! If you connect a serial cable, you will see what would have been displayed on the monitor. To get back to normal you need to set "stdout" back to "vga".
I don't understand why you set stdout to serial but if by this you wanted to enable some output to serial, you don't need it. Uboot always output the very first lines of hardware initialisation to the serial connector.
I mean the lines starting with:
U-Boot 2015.a1 (May 28 2015 - 20:32:28)
CPU: AMCC PowerPC 460EX Rev. B at 1210 MHz (PLB=217 OPB=121 EBC=121)
No Security/Kasumi support
Bootstrap Option H - Boot ROM Location I2C (Addr 0x52)
Internal PCI arbiter enabled
32 kB I-Cache 32 kB D-Cache
