Subject: smbios: Set BIOS release version
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7617f996e6a83672fd7289103fe3fc52ff10007e;p=u-boot.git

smbios: Set BIOS release version

We may as well include the U-Boot release information in the type-0 table
since it is designed for that purpose.

U-Boot uses release versions based on the year and month. The year cannot
fit in a byte, so drop the century.
