Starting from OpenSBI v0.7, the SBI firmware inserts/fixes up the reserved memory node for PMP protected memory regions. All RISC-V boards needs to copy the reserved memory node from the device tree provided by the firmware to the device tree used by U-Boot.
Turn on CONFIG_OF_BOARD_FIXUP by default for OF_SEPARATE.
