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.
Best regards,
