still crawling through the code related to FDTs, and while i see a
pile of boards that define CONFIG_OF_SYSTEM_SETUP, i see very few that
define the corresponding(?) ft_system_setup() routine.
$ grep -r CONFIG_OF_SYSTEM_SETUP *

and yet ...
$ grep -rw ft_system_setup *

Kconfig: This causes U-Boot to call ft_system_setup() before booting
into
README: This causes ft_system_setup() to be called before booting
$
am i missing something? what is the point of a board defining that
setting but not defining the associated(?) ft_system_setup() function?
what else is that CONFIG setting being used for? thanks.
