Details

zoneinfo lists information about memory zones.

Supportdata2 includes zoneinfo in the Meminfo section since sd2-09.
In Supportdata-Probes it was never included (up to fw 7.39).

Excerpt from the proc(5) man page: 

/proc/zoneinfo (since Linux 2.6.13)

       This file displays information about memory zones.  This
       is useful for analyzing virtual memory behavior.

The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.
