Hi Arnd, Rob, Krzysztof

Sorry for being late. I was on vocation in the past several days.
As for this as370 removing, I think we'd better keep it. I planned
to submit the as370-rdk board dts two years ago, but latter I focused
on Synaptics SoCs related drivers support such as gpio, pcie, sdhci and
so on. I will send a basic as370 rdk board dts. I'm also considering
to mainline basic support for a new SoC.

Thanks
