You can either boot an OS (or some other application),  where  "boot"
means  that the only way back into U-Boot is through a systemn reset;
or you can load and start a "standalone application",  which  returns
to U-Boot after execution.

Yes, it can (depending on the exported U-Boot functions). See the docs.

Define "iterative server"!

In case of  a  stndalone  application:  yes  (unless  you  crash  the
system).
