In a SoC based solution, it would be useful to know the versions of the
various binary firmware blobs the system is running on. On a QCOM based
SoC, this info can be obtained from socinfo debugfs infrastructure. For
this to work, respective subsystem drivers have to export the firmware
version information to an SMEM based version information table.
Having firmware version information at one place will help quickly
figure out the firmware versions of various subsystems on the device
instead of going through builds/logs in an event of a system crash.
Fill WLAN firmware version information in SMEM version table to be
printed as part of socinfo debugfs infrastructure on a Qualcomm based
SoC.
This change is applicable only for SNOC/QMI based targets.
Example:
cat /sys/kernel/debug/qcom_socinfo/cnss/name
QC_IMAGE_VERSION_STRING=WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1
Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1
