'How to port FreeRTOS to a core without an interrupt controller

I am working on a project which involves porting FreeRTOS to a custom SoC. This SoC features a Cortex R5 core together with an FPGA fabric. Unfortunately, the R5 core comes without any interrupt controller (neither GIC nor VIC).

Is there anything I can do here? (Other than writing my own interrupt controller).
