So I've had one of these for a while and it looks like the vendor never bothered submitting the support upstream. This adds it using ppc40x_simple and provides a device-tree. There are some changes to the boot wrapper because the way u-boot works on this thing, it seems to expect a multipart image with the kernel, initrd and dtb in it. The USB support is missing as it needs the yet unmerged driver for the DWC OTG part and the GPIOs may need further definition in the dts.
