Hi Rama Devi,
XILSEM edac device is present on Versal and Versal NET SOCs.
https://docs.amd.com/r/en-US/oslib_rm/Tool-Configuration-for-XilSEM
(Actually also on Versal Gen 2 but firmware interface is going to be different).

I don't think we should try to integrate EDAC memory controller with EDAC
device because their usage is independent of each other.

Are you saying that you will have this XILSEM hw in different platforms?

IOW, you will have a Versal or Versalnet thing and then something else, and
then XILSEM will be in all of them?

Then perhaps it is better to have it as a separate EDAC "driver". In air
quotes because this is not really a driver but simply a wrapper so that it can
be called an EDAC driver.

It all depends on what hw configurations will be built.

The v2 [1] had a separate XilSEM EDAC driver. Are you planning to revive this?
But if you have XILSEM *only* with Versal, then I don't want a separate EDAC,
hm, driver.
