This series adds an initial support for Rockchip SoCs and has been tested on a Radxa Rock board, on which I'm able to load a kernel from the network and boot it [1]. At the moment Barebox must be chainloaded from the Rockchip binary bootloader which performs low-level initializations and loads Barebox from the "boot" partition on the NAND. Barebox should be written using the same procedure used for kernels: it must be prepared with the mkimage tool and then written with rkflashkit. There is a u-boot code released by Rockchip [2] which probably includes all the low-level initializations but I'm not brave enough to try it. The patchset adds ethernet and pinctrl drivers, PLL and clocks initialization, and code to power on the external PHY of the board through the PMIC.
