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.
