Initial support for running FreeBSD on the Nintendo Wii. We're able to reach single user mode using a memory disk device as the file system. This port includes the framebuffer driver, the PIC driver, a platform driver and the GPIO driver. The IPC driver (to talk to IOS kernels) is not yet written but there's a placeholder for it. There are still some MMU problems and to get a working system you need to patch locore32.S. Since we haven't found the best way yet to address that problem, we're not committing those changes yet. The problem is related to the different BAT layout on the Wii and to the fact that the Homebrew loader doesn't clean up the special registers (including the 8 BATs) before passing control to us. You'll need a Wii with Homebrew loader and a TV that can do NTSC (for now). Submitted by: Margarida Gouveia 2012-08-21 06:31:26 +00:00			`/*-`
