[U-boot] bridge_enable_handoff failed to run

When I run printenv bridge_enable_handoff, I'm receiving the following:

bridge_enable_handoff=mw $fpgaintf ${fpgaintf_handoff}; go $fpga2sdram_apply; mw $fpga2sdram ${fpga2sdram_handoff}; mw $axibridge ${axibridge_handoff}; mw $l3remap ${l3remap_handoff}

The "application terminated, rc = 0x0" occurs when I run the 'go $fpga2sdram_apply' command.

So, how to fix?

Actually I want to make the read/write accesses to/from AXI3 lightweight bridge.
