rockchip: rk3188: Add Radxa Rock board
Browse files Browse the repository at this point in the history 
The Rock is a RK3188 based single board computer by Radxa.
Currently it still relies on the proprietary DDR init and
cannot use the generic SPL, but at least is able to boot
a linux kernel and system up to a regular login prompt.
