    firmware: dmi_scan: add SBMIOS entry and DMI tables · d7f96f97
    Ivan Khoronzhuk authored
    Some utils, like dmidecode and smbios, need to access SMBIOS entry
    table area in order to get information like SMBIOS version, size, etc.
    Currently it's done via /dev/mem. But for situation when /dev/mem
    usage is disabled, the utils have to use dmi sysfs instead, which
    doesn't represent SMBIOS entry and adds code/delay redundancy when direct
    access for table is needed.
    
    So this patch creates dmi/tables and adds SMBIOS entry point to allow
    utils in question to work correctly without /dev/mem. Also patch adds
    raw dmi table to simplify dmi table processing in user space, as
    proposed by Jean Delvare.
