I see that there is a CLIC branch available here:
https://github.com/riscv/riscv-qemu/pull/157

It looks like all of the work is in a single commit
(https://github.com/riscv/riscv-qemu/pull/157/commits/206d9ac339feb9ef2c325402a00f0f45f453d019)
and that most of the other commits in the PR have already made it into
master.

Although the CLIC commit is very large it doesn't seem impossible to
manually pull out the CLIC bits and apply it onto master.

Do you know the state of the CLIC model? If it's working it shouldn't
be too hard to rebase the work and get the code into mainline.
