That's up to you. Mainboard manufacturer, along with product name, serial
number, and version, are strings which are expected to be assigned by the
vendor. You may set these in your mainboard's Kconfig file. The Macbook 2.1
port shows an example of how to do this:
https://review.coreboot.org/cgit/coreboot.git/tree/src/mainboard/apple/macbo...
.

Other SMBIOS tables such as memory info is generated automatically by
coreboot. For example, the type 4 table should have details about your
processor manufacturer (Intel) as well as information which implies
Baytrail (CPU family, model, and stepping).
