[seL4] Status of the seL4 RISC-V platform Rocketchip

Hi,

I'm wondering about the state of the seL4 RISC-V platform "Rocketchip", is anybody actively using this? At the seL4 hardware status page https://docs.sel4.systems/Hardware/rocketchip.html there is not much, and the repo https://github.com/ucb-bar/fpga-zynq has been abandoned. It points to https://github.com/sifive/freedom which has also been abandoned recently.

So I wonder, is this platform effectively dead and should be removed?
