Correct. You need the documentation and quite possibly also some
reverse engineering to create a working firmware. You can also
reverse engineer away the need for documentation, but that always
takes (much) longer.
Of course you can try to simply run some existing code, but it's a
little like compiling code for the wrong ISA. The registers are not
the same, so the existing init code does not make sense on another
hardware. Sometimes if the components happen to be similar you may
have limited success, but it is difficult to measure success until
e.g. a serial port or USB debug communications channel is working..
