	hex "physical eraseblock size"
	default 0x20000
	help
	  Tells ubinize the physical eraseblock (PEB) size of the
	  flash chip the ubi image is created for. The value provided
	  here is passed to the -p/--peb-size option of ubinize.

	bool "Use custom config file"
	help
	  Select this option to use a custom ubinize configuration file,
	  rather than the default configuration used by Buildroot (which
	  defines a single dynamic volume marked as auto-resize).  Passing
	  a custom ubinize configuration file allows you to create several
	  volumes, specify volume types, etc.

	  As a convenience, buildroot replaces the string
	  "BR2_ROOTFS_UBIFS_PATH" with the path to the built ubifs file.
	  So the volume defined for the root filesystem can specify the
	  image path as:  image=BR2_ROOTFS_UBIFS_PATH

config BR2_TARGET_ROOTFS_UBI_CUSTOM_CONFIG_FILE
	string "Configuration file path"
	depends on BR2_TARGET_ROOTFS_UBI_USE_CUSTOM_CONFIG
