 * You should really look at supporting buildroot (https://buildroot.org/)
*and* OpenEmbedded / yocto (https://www.openembedded.org/wiki/Main_Page //
https://www.yoctoproject.org/). These two are probably the most well known
tools for creating embedded distributions and will be familar to most
embedded developers.

 * The other big thing that would be awesome to see is Debian support.
Looking at https://wiki.debian.org/SH4, I'm assuming that is waiting for
you to support SH4 instructions?

Keep up the good work.
