I noted a commit "8df4ef3eaa62b" that accoring to Daniel's reminder.

That commit "8df4ef3eaa62b" patch said "Since commit 0166dc11be91 ("of:
make CONFIG_OF user selectable"), it is possible to test-build any
driver which depends on OF on any architecture by explicitly
selecting OF. Therefore depending on COMPILE_TEST as an alternative is
no longer needed."

Thanks.
