I found some comments in one of the files, so you could use these as a
base. Whenever you change code, you should make sure it has function
comments, follows style, etc. That way things slowly get better.

/*
 * Implement a weak default function for boards that need to do some final init
 * before the system is ready.
 */
__weak void board_final_init(void)
{
}

/*
 * Implement a weak default function for boards that need to do some final
 * processing before booting the OS.
 */
__weak void board_final_cleanup(void)
{
}

Simon

Applied to u-boot-dm, thanks!
