This series adds initial TPL support for Pine64 Rock64 board.
The ROCK64 is a credit card size SBC based on Rockchip RK3328 Quad-Core ARM Cortex A53.
The series has been tested with ATF v2.1.
Some patches in the series are taken from https://github.com/rockchip-linux/u-boot Credits are given in each patch separately.
Changes since v1:
- Added commit message in patch 6
- Split config to rk3328/Kconfig in patch 4
- Introduced rk3328-evb-u-boot.dtsi to collect u-boot specific dts configs

It correctly boots up to a U-boot prompt on my Rock64. However it fails to read data correctly from the SD card afterwards:

=============
If I manually load the kernel Image, that also fails. If I manually load the fdt file, it completes, but the data is complete gibberish. ls works fine though.
And removing the fifo-mode flag from arch/arm/dts/rk3328-rock64-u-boot.dtsi makes it not boot at all.
Previously I was using an old build from Armbian, and that worked fine.
