So far spl-boards have declared the back_to_brom() function as simple extern in the files themself. That doesn't scale well if every boards defines this on its own. Therefore move the declarations to a bootrom header. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Kever Yang <kever.yang@rock-chips.com>
