Where does this "mini program" get the data?  It will face the same
issues I outlined in my previous email.

The coreboot table today does not provide sufficient information to
build the acpi/pir/mptable/smbios tables.

We could extend the coreboot table - but what's the point of defining
our own intermediate format.  For example, if the end consumer wants
an smbios table, why translate from "coreboot->coreboot
table->legacybios->smbios table" when we can just go from
"coreboot->smbios table"?

Adding an additional program in between seems to make things more
