The compiler is not happy when neither USB nor TFTP transport for DFU defined:
cmd/dfu.c: In function ‘do_dfu’:
cmd/dfu.c:31:8: warning: unused variable ‘devstring’ [-Wunused-variable]
char *devstring = argv[3];
^~~~~~~~~
cmd/dfu.c:30:8: warning: unused variable ‘interface’ [-Wunused-variable]
char *interface = argv[2];
^~~~~~~~~
Surround those variables by #ifdef expression.
More serious, that comes under same circumstances, is a compilation error due
to absence of macro parameter:
In file included from include/image.h:45,
from include/common.h:35,
from cmd/dfu.c:13:
include/command.h:207:24: error: expected expression before ‘,’ token
# define _CMD_HELP(x) x,
^
include/command.h:286:18: note: in expansion of macro ‘_CMD_HELP’
_cmd, _usage, _CMD_HELP(_help) _CMD_COMPLETE(_comp) }
^~~~~~~~~
include/command.h:290:3: note: in expansion of macro ‘U_BOOT_CMD_MKENT_COMPLETE’

include/command.h:332:2: note: in expansion of macro ‘U_BOOT_CMD_COMPLETE’
U_BOOT_CMD_COMPLETE(_name, _maxargs, _rep, _cmd, _usage, _help, NULL)
^~~~~~~~~~~~~~~~~~~
cmd/dfu.c:70:1: note: in expansion of macro ‘U_BOOT_CMD’
U_BOOT_CMD(dfu, CONFIG_SYS_MAXARGS, 1, do_dfu,
^~~~~~~~~~
make[1]: *** [scripts/Makefile.build:279: cmd/dfu.o] Error 1
make: *** [Makefile:1518: cmd] Error 2
Put empty string unconditionally to have macro parameter present.
