SERIAL:
	WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
        The Serial setting is 115200-8-N-1. The board has a populated
        right angle 1x4 0.1" pinheader.
        The pinout is: VCC, RX, TX, GND.

Odd stuff:
	- uart0 clock frequency is 62.5 MHz.

	  because of the silkscreen on the PCB.
	- the original u-boot has been compiled with most functions
