This isn't in FreeBSD yet. True. One of the directions would be looking at NetBSD code, as they have some ppc405 support (at least Walnut platform was supposed to run when I last looked it it). >> I want to know how the bootloader should also be. > > Looks like u-boot supports the ml403, and with u-boot now supporting > FreeBSD, that should be the place to start. Yes, and getting the loader to work should be a pretty easy step: our existing PowerPC loader(8) for U-Boot should run as is in most cases: it's known to work on MPC85xx (e500) and MPC83xx (e300) and I don't see why this code would not run on other PowerPC variations.
