I was originally planning on using the Linux binary (I've been doing all of my testing so far with the Linux binary) but if you have patches for FreeBSD I think that's likely the best way forward, or it may make sense to import both? Then, I'd like to get the Goldfish code into the main FreeBSD tree. It would be nice to get at least bidirectional UART working before we can do that, are there any issues with the emulator that would prevent this? I've also not managed to get ethernet or the framebuffer working, though I've not looked deep into this and especially for the network interface it may be related to how I'm running the emulator - I guess you have been passing through a device into the emulator? I think once we can get the bidirectional UART fully functional, we can push this into the tree. Also, goldfish_mmc.c is missing a copyright statement - can you add one please? Thanks, Gavin
