    wifi: ath10k: Store WLAN firmware version in SMEM image table · 4d79f6f3
    Youghandhar Chintala authored
    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
