TMDSSK3358: DDR software leveling was performed or not on TMDSSK3358 ?

Part Number: TMDSSK3358

I'd like to know whether DDR software leveling was performed or not on TMDSSK3358.

According to sprr356a, 16bit DDR3 (MT41J128M16JT-125) memory device is implemented on TMDSSK3358. (Fig.1)
My understanding is that software leveling descried in "AM335x_EMIF_tool_sprack4.pdf" is not needed for TMDSSK3358 because only one 16bit DDR3. (Fig.2)
So, I think that u-boot source code implemented these four values (.datardsratio0, .datawdsratio0, .datafwsratio0, .datawrsratio0 in Fig.3) from EMIF tool, not the results of software leveling.

Is my understanding correct ?
