[Qemu-devel] [v4 PATCH 05/12] SMBIOS: Build full tables for types 0 and 1

["Gabriel L. Somlo" <gsomlo@gmail.com>]

Build full tables for types 0 (bios information) and 1 (system
information). Type 0 is optional, and a table will only be built
if requested via the command line; the default is to leave type 0
tables up to the bios itself.
