This function seems to not be called if you do NOT define BINMAN_FDT 
Kconfig option. Is this something you could check? I see that STM32 
boards and some Mediatek ones have this disabled. The benefit would be 
to still have binman build the images like all other rockchip platforms 
but let your RK336x board boot properly.

I'm wondering what this binman_init is needed for? It seems to me that 
the functions defined in lib/binman.c are actually used only in x86
