support of rockchip nanopiM4 2GB board

Hi Jagan,

upstream uboot has the support for nanopi M4 board with 4GB LPDDR3 RAM. I have a nanopi M4 board with 2GB DDR3 RAM and able to boot this board by using ddr3 configuration.

how to handle this situation? do we need to treat this as a new board support?
