OpenSPARC is another one in this space. I was working on a wifi daughter board for a project a while ago that had a SPARC at its heart. It really made sense for them. They were already in the business of fabing their own complicated ICs, they didn't need a really power CPU and power wasn't a huge concern to them. So they got a pretty decent CPU with mature tooling without the licensing to ARM. These are only my guesses at their logic though. I was just an outsider looking in at a closed black box.
