-new uBoot commands:
-
-status in[it]		setup GPIOs
-status ge[t]		get button status
-status se[t] hh		set LEDs to lower 4 bit
-status se[t]		increment last state, i.e. make LEDs count
-status mi[rror]		read button status and mirror to LEDs until a key is pressed
-status bl[ink]		blink LEDs
-
-lcm in[it]			initialize subsystem (DSS, GPIOs etc.)
-lcm ba[cklight] dd	set backlight level (0..255)
-lcm po[wer] dd		set power level (0..2)
-lcm on				set lcm on
-lcm of[f]			set lcm off
-
-gps on | of[f]		control GPS receiver (and initialize UART)
-gps re[ad]			read GPS NMEA from UART until a key is pressed
-
-tsc init			initialize/enable TSC2007 through I2C2
-tsc get				read current ADC values (incl. internal temp and AUX/photosensor)
-tsc lo[op]			read x/y coordinates
-tsc ch[oose]		somehow allow to define receptive fields and use the result to select different boot options
