Sometimes it is useful to jump into U-Boot directly from coreboot or UEFI without any 16-bit init. This can help during development by allowing U-Boot to avoid doing all the init required by the platform. U-Boot expects its GDT to be set up correctly by its 16-bit code. If coreboot doesn't do this (because it hasn't run the payload setup code yet) then this won't happen. In this case we cannot rely on the GDT settings. U-Boot will hang or crash if these are wrong. Provide a development-only option to set up the GDT correctly. This is just a hack so you can jump to U-Boot from any stage of coreboot, not just at the end.
