Incorporating also Mike's suggestion for the one-line help, I propose this:

U_BOOT_CMD(
	tftpsrv,        2,      1,      do_tftpsrv,
         "act as a TFTP server and boot the first received file",
         "[loadAddress]\n"
         "Listen for an incoming TFTP transfer, receive a file and boot it.\n"
         "The transfer is aborted if a transfer has not been started after\n"
         "about 50 seconds or if Ctrl-C is pressed."
);
