UART4 not responding but UART2 does

Hi! All,

We add the following lines on mx53_loco.c and create the image.

------------------------

    /* UART2 */
    MX53_PAD_PATA_BUFFER_EN__UART2_RXD_MUX,
    MX53_PAD_PATA_DMARQ__UART2_TXD_MUX,
    /* UART4 */
    MX53_PAD_CSI0_DAT12__UART4_TXD_MUX,
    MX53_PAD_CSI0_DAT13__UART4_RXD_MUX,
-----------------------

We also wire these UART to a port on PC.  Apparently we could open UART2 port with ssh but UART4 does not show any response.  Can anyone tell us what we did wrong to enable UART4?
