        Rarely, it is useful to disable the request that flash driver code

        be copied to separate RAM for execution.  This option lets you do that.

        It should only be controlled by redboot_XXX.ecm config files, for

        building different varieties of RedBoot.

        NEVER disable this option for ROM startup code, which executes in place

        from Flash: the build will not work."
