IFF that is all you want to do is have a new kernel. In which case, there's no need to modify booting etc. This information can be readily found in the handbook. If, however, you want to make an image that you can burn onto an uSD card, then crochet is a good place to start: https://github.com/freebsd/crochet. This approach will be faster than building a kernel on an RPI (assuming you have an AMD64 machine running FreeBSD, that is). Cheers Matt.
