Rasperry pi 4 DRAM address mapping

[frederick00]

HI Everyone,

I need help about DRAM address mapping on Rasperry pi 4 especially my question is : given two physical memory addresses how can i know if they are in the same DIMM, Rank and Bank ?
is there any bit to check for it ?

Thank you.

Pis don't use DIMMs, so your question doesn't apply to them.
