Research direction
Compare libcpu/risc-v/t-head/c906/plic.c, libcpu/risc-v/t-head/c908/plic.c, and libcpu/risc-v/virt64/plic.c to identify their shared PLIC driver behavior and platform-specific differences. The work is done when the three separate implementations are unified into one implementation without losing support for the listed RISC-V targets.
