In this general form, the statement is wrong.

Depending on architecture, U-Boot does implement and use  interrupts.
It  even exports an interface to standalone applications which allows
to register custom interrupt handlers.

It's just just most U-Boot drivers do not use interrupts but polling
mode - note that there are exceptions from this rule, too.
