The input for mkimage can be tpl alone. 
I think this case is for rksd. For rksd one can simply concatenate 
the output of mkimage -n rk... -T rksd tpl  with the spl binary. 
That's why u-boot-spl is out of mkimage when there's u-boot-tpl.
for rksd I think mkimage just adds a header in front of the binary, 
so you can put the next binary right behind. You don't have to give spl 
to mkimage if you give it tpl.
