The module is quite simple with only a few (almost) fixed regulators and a eMMC on-board. The eMMC is currently limited to 50MHz modes via the pinctrl, as the board has not wired up the data strobe line, which prevents HS400 mode from working. As both the controller and the eMMC support this mode, it is automatically selected when we allow the faster modes, leading to failing transfers. Until we have a proper solution to only disable HS400 mode, keep the eMMC at the slow bus modes.

Not all of the board periperals are enabled yet, as some of them still require kernel patches to work properly. The nodes for those peripherals will be added as soon as the required patches are upstream. The following has been tested to work: - UART console - SD card - eMMC - Gigabit Ethernet - USB (internal Keyboard, Mouse, external ports) - M.2 PCIe port Co-developed-by: Lukas F.
