this is exactly the same as the normal t440p config,
except that cbfs is 4mb instead of 8mb.
this is useful when externally updating libreboot,
or unbricking; it could also be used for lazier
installation, where you only flash the 2nd chip
without doing a disassembly to get at the other one,
if the user didn't care about neutering the ME.
