Submodule checkout fails - do you need to push to ibex_wb?

Hi,

I saw this project via your Exit MIG, Enter LiteDRAM blog post, mentioned on HN. It's really exciting to see so many build-your-own-computer-on-an-FPGA projects around these days, and I was keen to take a look and try it out - but the "make setup" step fails when checking out submodules, like so:

fatal: remote error: upload-pack: not our ref 5e3d258294478e1352edaba336b1c0640a188037
fatal: the remote end hung up unexpectedly
Fetched in submodule path 'sub/ibex_wb', but it did not contain 5e3d258294478e1352edaba336b1c0640a188037. Direct fetching of that commit failed.

I guess you have work in your fork of ibex_wb that you haven't pushed yet?
