[PATCH 00/11] ARM: add initial support for Rockchip boards

[Beniamino Galvani]

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.
