This core is found on many HiSilicon chips. This patchset adds support for it and the integrated MDIO bus.
The driver code comes from linux kernel driver, downstream u-boot driver and the datasheet. It's already tested on a Hi3798MV200 based STB. Note that currently this driver can't be used for Hi3798MV200 since the clock driver is missing. I will implement and submit the clock driver and the framework in a later patchset.
