[dmidecode] [Patch v2 0/2] firmware: dmi-sysfs: add SMBIOS entry point area raw attribute

[Ivan Khoronzhuk]

Some utils, like dmidecode and smbios, needs 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. So this patch series adds SMBIOS
area to dmi sysfs in order to allow utils in question to work
correctly with dmi sysfs.
