Author: manu Date: Thu Jun 14 06:28:09 2018 New Revision: 335112 URL: https://svnweb.freebsd.org/changeset/base/335112 Log: if_dwc_rk: Add DesignWare driver for RockChip SoCs. Add driver for the designware ethernet controller found in some RockChip SoCs. The driver still rely on a lot of things setup by the bootloader like clocks and phy mode. But since netbooting is the only/easiest way to boot rockchip board at the moment add the driver so other people can test/dev on thoses boards.
