[U-Boot] does it make sense to define misc_init_r() not conditional on CONFIG_MISC_INIT_R?

another oddity i noted in my travels ... in common/board_r.c, this:

#ifdef CONFIG_MISC_INIT_R misc_init_r, /* miscellaneous platform-dependent init */ #endif

suggests that any *definition* of a board's misc_init_r() routine should be similarly conditional, but there are well over a hundred counter-examples like, say, this from km83xx.c:

int misc_init_r(void) { ivm_read_eeprom(ivm_content, CONFIG_SYS_IVM_EEPROM_MAX_LEN); return 0; }

doesn't hurt, of course ... binary just ends up containing a superfluous misc_init_r() routine that's never called. i suspect there's a lot of that with other routines as well.

or is there something else going on here more subtle that i don't understand?
