In terms of peripherals the rk3368 is quite similar to the rk3288, which makes it possible to have a lot basic components working in the first go. More to follow once I tracked down all the tiny differences that still exist in some parts. With these dts files, the R88 board is able to boot from an attached usb device and most likely from its emmc too, if the emmc uses a standard partition table instead of Rockchip's own one - the emmc itself is detected correctly.
