Hi everyone,

This series adds proper support for Firefly / Libre Computer ROC-RK3328-CC
single board computer.

The ROC-RK3328-CC from Firefly and Libre Computer Project is a credit
card size development board based on the Rockchip RK3328 SoC, with:

- 1/2/4 GB DDR4 DRAM
- eMMC connector for optional module
- micro SD card slot
- 1 x USB 3.0 host port
- 2 x USB 2.0 host port
- 1 x USB 2.0 OTG port
- HDMI video output
- TRRS connector with audio and composite video output
- gigabit Ethernet
- consumer IR receiver
- debug UART pins

Originally I started with Loic's patches, and syncing the device tree
files from Linux. That didn't get very far, with SPL failing to detect
the SD card. Examining the schematics and internal state of GRF and
GPIOs, I realized that the logic for the SD card power enable switch
is opposite that of what the SD card controller's SDMMC0_PWREN pin
would use. Instead, directly using the GPIO is required.

Thus this series creates a special target for this board to handle
muxing this specific pin to GPIO state. The GPIO is left in input mode,
letting the external pull-down work its magic.

Along the way, there are some clean-ups of existing dts files, moving
U-boot only features to -u-boot.dtsi files, and then a wholesale sync
from Linux. Only boards already existing in U-boot are synced. DT
binding header files are synced separately as there is already one
patch floating around. The DT sync also includes clean-up changes only
recently posted, and likely won't make it in for at least a few weeks.

Please have a look, and test if possible. I cc-ed a couple people that
showed interest in this board on mailing lists recently.

Regards
ChenYu
