SUPERH also has a clut224 logo, so I assume we can also default to no
for it.

My wild guess would be none. Furthermore, no one "needs" a logo. It is
just a fun thing to add. This is why the LOGO sub menu is turned off by
default and that none of the defconfig would automatically select a LOGO.

And so, because a user interaction is needed anyway, the few who still
want a monochrome or vga16 logo can turn the option back on just after
selecting the LOGO sub-menu.

I guess the same could be said in reverse: we could keep all the logo on
by default as it is now and the users who only need the clut224 can turn
off the monochrome and vga16. But let's go for the majority ;)

Well, if someone can come with the list you are looking for, I will
happily add it to the patch. We can wait for a couple weeks if you want,
no rush here!

Or your can already stage it in fbdev-next and I will send you a v2 as
needed. Maybe we will get more comments if this reaches linux-next?

Yours sincerely,
