firmware/dmi: Report DMI Bios & EC firmware release
Some vendors like HPe or Dell, encode the release version of their BIOS
in the "System BIOS {Major|Minor} Release" fields of Type 0.
This information is used to know which bios release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 65.27 bios is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/bios_release
65.27
[root@t1700 ~]#
Servers that have a BMC encode the release version of their firmware in the
"Embedded Controller Firmware {Major|Minor} Release" fields of Type 0.
This information is used to know which BMC release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 3.75 bmc release is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/ec_firmware_release
3.75
[root@t1700 ~]#
