[seL4] Multikernel in RISCV

Hello, I'm currently working with seL4 & Polarfire (RISCV) and I'm working with a single core at the moment (doing some testing and understanding how seL4 works). Polarfire has 4 cores and I'd like to start using all of them in a multikernel configuration (every hart running its own sel4 kernel). I've found the following RFC: https://sel4.atlassian.net/browse/RFC-17 where Kent McLeod has done some work (https://github.com/kent-mcleod/camkes-manifest/blob/kent/multicore2/master.x...) but only for ARM. Does someone know if the same approach will be taken for RISCV? or even better, if someone has already done it? Thanks, David.
