See "board/tqm8xx/load_sernum_ethaddr.c" - on these boards the unused space at the end of the last U-Boot flash sector is used: we store some data structure in the last 64 bytes of this sector containing the serial number, MAC address and som configuration information of the board.

And if you update U-Boot in the field these information get lost!?

By then the information has long been saved to the normal environment (it get's written with the first "saveenv"). You just have to make sure that the standard update procedure takes care to keep the old environment - but you want to do this anyway.
