uBoot Hardware Awareness

I'm trying to understand how uBoot knows where to find the necessary hardware and peripherals on the IMX6. For example, when I build the default image uBoot outputs over UART1, but is it possible to have default output on UART2, 3,.. etc. Is there something similar to the DTB that uBoot uses to know what hardware it has available?
