Please also provide a ATF implementation for the rk3308 :-)
[Not a requirement for getting this merged, but it would be
really cool to have sources for the full stack]

I think ramoops are more a per-board thing, like for the evb.
As they'll require cooperation with bootloaders to not mangle that
memory area. For this please also coordinate with Kever because
I somehow remember we have u-boot sometimes at 0x100000.

Please add a patch adding the rockchip,rk3308-grf compatible to
Documentation/devicetree/bindings/soc/rockchip/grf.txt

compatible = "rockchip,rk3308-detect-grf", "syscon"
+ add the rk3308-detect-grf to the binding

same as detect_grf

compatible = "rockchip,rk3308-i2c", "rockchip,rk3399-i2c";
Same for all i2c controllers.

there is no high_speed pinctrl defined for the Rockchip spi driver
in mainline, so this part should go away in a first step.
Same for the other spi controllers.

peripherals-req-type-burst is undocumented so likely some change to the
dma driver not yet upstream?

These resets don't seem to be defined in driver or binding?
Same for other i2s

Was this support to the network driver already submitted?
Because I wasn't able to find it in the gmac driver.
