Precisely a few weeks ago I've started playing around the idea of doing a or1k port. I've managed to build a stub-filled or32 kernel, and now I've dealing with the early CPU/MMU initialization. I'm targeting the architectural simulator (or1ksim), and I think is quite feasible as a project, but as I can only dedicate a few hours per week, I can't guarantee results. > (d) Porting NetBSD to FPGA board with SPARC CPU softcore (target CPU and > board is not specified) As we already have SPARCv8 support, this should be fairly easy. In fact, I've tried running a MRCOFFEE under TSIM (LEON3 emulator) and most of the hard and ugly low-level stuff (CPU, MMU, PIC...) seems to work without changes. I think we just need an OpenFirmware replacement, some device drivers, and the usual bunch of tweaks here and there. The bad news is that TSIM is proprietary software with a license fee. Perhaps Aeroflex Gaisler would donate some licenses for such a porting project, but I'm not sure about this. Sergio.
