These commits get the Geniatech XPI-3128 board working with its Rockchip RK3128 SoC. Working so far are clocks, pin control, USB 2, eMMC, SDMMC, ethernet, and rebooting.
I also wrote a driver for the Ambiq Artasie AM18X5 RTC found on this device which adds a battery-backed RTC. These depend on some RK3128-specific commits on top of U-Boot 2025.04 found in this U-Boot tree plus a couple local changes to the XPI-3128-specific DTS file: https://github.com/knaerzche/u-boot/tree/rk3128-wip I'm not sure how best to package this up for a u-boot port in our tree.
