I am working on a custom iMX6q board resembling the SABRE  AI Quad CPU card.   I am trying to boot my board using the Parallel NOR Flash.   I have generated the uboot image for the WEIM NOR Flash for  the Sabre AI board, however,i have found out that my debug  UART is connected to the UART1 port of the Processor whereas  in the Sabre AI, the debug port is UART4.   I have gone through the Linux BSP porting guide, and the Linux  User guide, but i did not find anything which tells me how to  make changes in the Uboot code so that i can change the debug  UART port. Can anyone help me in make the modifications?
