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.
