5 Get mainboard and BIOS info easily on the Loongson platform,

7 and BIOS version when there exists problems related with
10 The related structures are already defined in the interface
11 specification about firmware and kernel which are common
12 requirement and specific for Loongson64, so only add a new

29 By the way, using dmidecode command can get the similar info if there
30 exists SMBIOS in firmware, but the fact is that there is no SMBIOS on
31 some machines, we can see nothing when execute dmidecode, like this:
33 [root@linux loongson]# dmidecode
35 # No SMBIOS nor DMI entry point found, sorry.
