If you're referring to product info like part number, vendor, etc., then yes,
OpenBMC can show it.

Your host system must be sending SPD info into BMC as IPMI FRU. OpenPOWER
Firmware does that. Can't say for other types of hosts.

You must have a proper configuration for phosphor-ipmi-fru. Take a look at how
this is done for YADRO VESNIN:

https://github.com/openbmc/openbmc/blob/master/meta-yadro/meta-vesnin/recipes-phosphor/configuration/vesnin-yaml-config.bb

https://github.com/openbmc/openbmc/blob/master/meta-yadro/meta-vesnin/recipes-phosphor/configuration/vesnin-yaml-config/vesnin-ipmi-fru.yaml

The first number there is the FRU ID used by the host in IPMI Write FRU Data
