As expected... With CONFIG_GPIO_DAVINCI=y:

[    1.801528] clk: Disabling unused clocks
[    1.801885] sdhci-am654 fa00000.mmc: Got CD GPIO

So we just have the wrong PARTUUID and try to boot from the first partition.

And after fixing this in U-Boot there is a login: for LetuxOS :)

For comparison: the Udoo-Neo (i.MX6) says:
root at letux:~# ./cpu-speed
Number of threads: 1

So we can boot, but there is neither Ethernet nor USB networking.
And no HDMI nor USB. cpufreq also seems to be broken.

Will need more tweaking of the CONFIGs.
