ZC702 Preset parameters

In zc702_system_bd.tcl there are some lines that set different parameters for the processing_system7 instance "sys_ps7". Between these, the ZC702 preset, and the ZC702 board file there are around 200 parameters that get set. Most of these are pretty obvious in their purpose, but some I can't figure out ("C_ALL_INPUTS" for example). Are all these parameters and their effects comprehensively documented somewhere? Or do I just need to read through the processing_system7 code?
