Subject: [PATCH] arm64: rk3399: Add support NanoPi R4s

NanoPi R4s [1] is SBC base on Rockchip RK3399 hexa-core processor with
dual-Core Cortex-A72 and Mali-T864 GPU with 4GiB(LPDDR4) of RAM, SD card
support,
including 2 gigabit ethernet(RTL8211E 1Gbps - RTL8111H 1Gbps) and 2 USB 3.0
port.
port.It also has two GPIO headers which allows further peripherals to be
used.

The devicetree file is taken of the rk3399 nanopi4 Linux kernel [2].

we need a commit number in mainline kernel instead of file link.

This product is no need in the commit message.

Please don't add my review tag before I reply it to the list with 
"Reviewed-by..." message.

One more thing is that please make sure this patch can pass the 
checkpatch script, 10 warnings for this patch now,

and you will need to add MAINTAINERS info for this board at 
board/rockchip/evb_rk3399/MAINTAINERS if you

want to follow evb with everything other than dts, or else you will need 
to add a board at board/friendlyarm/.


Thanks,

- Kever
