Hello Chen and Inochi,
I'm really sorry, indeed, those nodes certainly don't work, it was a
mistake on my side introduced between v1 and v2.
However, I can ensure that "uart0" and "sdhci0" are working fine.
May I suggest to remove those two nodes? I can send a new iteration if
it's easier for you to handle?
