+What: /sys/firmware/lefi/boardinfo
+Date: October 2020
+Contact: Tiezhu Yang <yangtiezhu@loongson.cn>
+Description:
+ Get mainboard and BIOS info easily on the Loongson platform,
+ this is useful to point out the current used mainboard type
+ and BIOS version when there exists problems related with
+ hardware or firmware.
+
+ The related structures are already defined in the interface
+ specification about firmware and kernel which are common
+ requirement and specific for Loongson64, so only add a new
+ boardinfo.c file in arch/mips/loongson64.
+
+ For example:
+
+ [loongson@linux ~]$ cat /sys/firmware/lefi/boardinfo
+ Board Info
+ Manufacturer : LEMOTE
+ Board Name : LEMOTE-LS3A4000-7A1000-1w-V01-pc
+ Family : LOONGSON3
+
+ BIOS Info
+ Vendor : Kunlun
+ Version : Kunlun-A1901-V4.1.3-20200414093938
+ ROM Size : 4 KB
+ Release Date : 2020-04-14
+
+ By the way, using dmidecode command can get the similar info if there
+ exists SMBIOS in firmware, but the fact is that there is no SMBIOS on
+ some machines, we can see nothing when execute dmidecode, like this:
+
+ [root@linux loongson]# dmidecode
+ # dmidecode 2.12
+ # No SMBIOS nor DMI entry point found, sorry.
