Originally I did just document the RZ/N1 stuff, since I really have no 
experience or knowledge of the other ones. But it felt wrong to create 
"doc/board/renesas" containing only RZ/N1 information. So I tried to at 
least collect the names of the other Renesas boards from U-Boot sources.

I'll make the fixes you suggested, and will move the RZ/N1 details into 
their own file.

Indeed it does, see below. I did however want to document how to call 
mkimage manually, since it took me a while to work out the right 
arguments (especially using -n for the config file).
