extracts from arch/arm/lib/board.c:

#if defined(CONFIG_ARCH_CPU_INIT)
	arch_cpu_init,		/* basic arch cpu dependent setup */
#endif
#if defined(CONFIG_BOARD_EARLY_INIT_F)
	board_early_init_f,
#endif
#if defined(CONFIG_ARCH_MISC_INIT)
	/* miscellaneous arch dependent initialisations */
	arch_misc_init ();
#endif
#if defined(CONFIG_MISC_INIT_R)
	/* miscellaneous platform dependent initialisations */
	misc_init_r ();
#endif
#ifdef BOARD_LATE_INIT
	board_late_init ();
#endif
#if defined(CONFIG_RESET_PHY_R)
	debug ("Reset Ethernet PHY\n");
	reset_phy();
#endif

Just a few that can be "enabled" by board specific defines.

"xxxboard".h #defines them and "xxxboard.c" has to implement them.

Best Regards,
Reinhard
