Of course it can. If you had read the manual, you should  have  found
the  section about standalone applications. And of course it can boot
a couple of other operating systems as  well,  which,  from  U-Boot's
point of view, are just different applications.

If you want to avoid U-Boot's hardware init, then run your application
on the raw hardware without U-Boot. But be prepared that then you have
to reinvent all the needed hardware init steps yourself.

May I suggest that you just read the related sections in the  manual?
It  comes  with  a couple of examples which show exactly what you are
asking for.
