Ok, in order to achieve 5760, you're going to have to change the UART
frequency. Change the clock source, multiplier, etc.

You can also put a newer debian image on the eMMC, and configure uEnv.txt
to boot from sdcard.
However, in the above case you'd still be loading MLO( and possibly uboot

DO you need to compile your own module(s)? If not then any of the latest
