This also depends on !x86-64 ramstage since the implication is that ramstage is entered with CAR still enabled.

I think we should be explicit in the commenting how exit_car.S needs this section for obtaining the stack value. ENV_POSTCAR and RAMSTAGE_LOADS_FROM_ROMSTAGE both need this section because exit_car.S is the stage entry point which needs that information.
