Please also provide a ATF implementation for the rk3308 :-)

really cool to have sources for the full stack]
Tony's team has the plan to do it.

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.
I removed it in V2.

there is no high_speed pinctrl defined for the Rockchip spi driver
