How come that the SH port of the linux kernel is cooperating with
Redboot? Is it because the ones who initiated the SH port of the linux
kernel had choosen redboot as their boot loader? Or has this been added
afterward?
Do you have any ideas of how dificult it would be to have this same
cooperation for other linux kernel ports, eg i386 or arm ?
