From: Christopher Obbard <chris.obbard@xxxxxxxxxxxxx>
Add board file for the RK3588 Rock 5B board. This is a basic
implementation which just brings up the eMMC and UART which is
enough to successfully boot Linux.
The ethernet controller is connected via PCIe so support will
come in a follow-up patch.
