Because they are required by Linux.

maybe but legacybios has a lot of things coreboot (for Linux) doesn't 
need. They are required for other OS.

Then that payload has to have the knowledge of every cpu, chipset, and 
motherboard configuration to extract the information. That is difficult 
which is why the OS leaves it up the the BIOS. It make sense that the 
tables are generated and used by the configuration code.
