rockchip: board: Add support for KICKPI K1

The KICKPI K1 is a RK3568B2-based single board computer with eMMC, microSD card slot, dual Gigabit Ethernet (Maxio MAE0621A PHYs with on-board crystals) and a 1500000 baud serial console on UART2.

Add a minimal device tree enabling eMMC, SD-card, UART2, USB OTG and both GMACs, together with a defconfig to boot from eMMC or SD-card.

Hi Yuming Chen,

We do not accept downstream Device Trees for Rockchip boards anymore. Please work with the Linux kernel to have this Device Tree upstreamed, then once it's merged and available in https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing.git/, you can add support for it in U-Boot by cherry-picking the Device Tree with

./tools/update-subtree.sh pick dts <commit_hash>

Cheers,
Quentin

Hi Quentin,

Thanks for the clarification. Understood -- I will take the Device Tree to the Linux kernel first and resubmit the U-Boot board support once it is available in devicetree-rebasing.

Best regards,
Yuming Chen
