I'm trying to reconfigure our custom board based upon the SabreAuto (iMX6Q) to use a different UART for serial console for u-boot and Linux. I have been unable to locate any real instructions on how this can be accomplished but have derived a lot of it by reading the processor manuals and examining code. I have been unable to locate some of the definitions in the code even with exhaustive searching. Specifically, I cannot find the following definitions.
Could someone point out where I can find these symbols and also some better instructions on how to reconfigure U-Boot/Linux to a different set of PADS.
