The RCORE looks like a carrier board for the Firefly iCore RK3588Q SoM [1]. So it would be better to restructure the DTS as a dtsi for the SoM and a board DTS which includes the SoM dtsi. That's similar to the structure of the Firefly ITX-RK3558J board which uses the rk3588-firefly-core-3588j.dtsi.
