[U-Boot] in cmd_df.c, why does U_BOOT_CMD reference cmd not defined in that file?

[Robert P. J. Day]

  always willing to embarrass myself with silly questions, what is
going on in cmd_df.c?  note the command defined is apparently "sf",
which invokes something called "do_serial_flash", which is nowhere to
be seen here:

/*
 * Command for accessing DataFlash.
 *
 * Copyright (C) 2008 Atmel Corporation
 */
#include <common.h>
#include <df.h>

static int do_df(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[])
{
	const char *cmd;

	/* need at least two arguments */
	if (argc < 2)
		goto usage;

	cmd = argv[1];

	if (strcmp(cmd, "init") == 0) {
		df_init(0, 0, 1000000);
		return 0;
	}

	if (strcmp(cmd, "info") == 0) {
		df_show_info();
		return 0;
	}

usage:
	return CMD_RET_USAGE;
}

U_BOOT_CMD(
	sf,	2,	1,	do_serial_flash,
	"Serial flash sub-system",
	"probe [bus:]cs		- init flash device on given SPI bus and CS")


  i'm confused ...
