How I see this can be integrated in QEMU is creating a Dockerfile
starting with "FROM qemu:debian-mips64el-cross" then a bunch of "RUN"
lines which do the same as your script and finally generates the
pmon.bin which we'll add to repository and ship as roms/pmon_2e.bin.

This doesn't seem PMON related but a feature of the fulong2e that QEMU
doesn't model yet.
