	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."
