Well, it happens if for each maintained board there is a corresponding
logo and all logos should be maintain in U-Boot repository - that is
quite a mess.

Logos has nothing to do with U-Boot development - they are blob data.
The fact that they are linked together with U-Boot looks easy, but I do
not think it is elegant.

Splash images are loaded on demand by u-boot code from a storage - this
is IMHO a better solution.

Maybe due to the number of boards, and if each board wants to have its
own logo. If all boards share the same logo I would not see any problem
at all.

ok, you like really the logo feature, I see ;-).

Added Anatolji to CC - we could let the question in background for the
future.  Maybe could we have a logo_load_image() near splash_load_from_*() ?
