In that case there must be some threads that continuously check for pending requests from UART, ETHERNET or so ..
Threads? U-Boot is not an full blown OS. No threads are needed in this bootloader.
But I don't find any sort of threading inside u-boot code
U-Boot "sits" there and waits for some input from the console, or for an ethernet reply packet. This can be done using polling without any performance penalty.
