config DRVR_MKRD
	bool "RAM disk wrapper (mkrd)"
	default n
	---help---
		Build the mkrd() function which serves as a wrapper to simplify
		creation of RAM disks.  If the boardctrl() interface is enabled,
		the selecting this option will also enable the BOARDIOC_MKRD

	int "Write flush delay"
	default 350
	---help---
		If there is no write activity for this configured amount of time,
		then the contents will be automatically flushed to the media.  This
		reduces the likelihood that data will be stuck in the write buffer
		at the time of power down.
