Hi All,

 We woukld like to get opion on below multi-host support approaches.

Background :
------------
  The Phosphor-post-code-manager supports only host 
to store/retrieve the host postcode history.

Approaches:
-----------
Approach 1: << run the multiple process >>

Create and run the multiple phosphor-post-code-manager process to handle each host postcode history.

   xyz.openbmc_project.State.Host0.Boot.PostCode
   xyz.openbmc_project.State.Host1.Boot.PostCode
   xyz.openbmc_project.State.Host2.Boot.PostCode
   xyz.openbmc_project.State.Host3.Boot.PostCode

Approach 2: << pass number of host to single process >>

Pass number of host to single process phosphor-post-code-manager to register dbus object 
and handle each host postcode.

   xyz.openbmc_project.State.Host0.Boot.PostCode
   xyz.openbmc_project.State.Host1.Boot.PostCode
   xyz.openbmc_project.State.Host2.Boot.PostCode
   xyz.openbmc_project.State.Host3.Boot.PostCode


Thanks
