strcpy analysis of u-boot: exploitable?

./tools/easylogo/easylogo.c:
	strcpy (inputfile, argv[optind]);
		strcpy (varname, argv[optind + 1]);
		strcpy (outputfile, argv[optind + 2]);

./common/cmd_nvedit.c:
			strcpy(message + pos, argv[i]);

./common/cmd_bootm.c:
		strcpy(dest, argv[i]);

./common/cmd_pxe.c:
		strcpy(bootm_argv[2], getenv("ramdisk_addr_r"));
