- Build an ubi image from the ubifs one (with ubinize).

- 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.
- config BR2_TARGET_ROOTFS_UBI_SUBSIZE
- int "sub-page size"
- default 512
- help
- Tells ubinize that the flash supports sub-pages and the
- sub-page size. Use 0 if sub-pages are not supported on flash
- chip.
- The value provided here is passed to the -s/--sub-page-size
- option of ubinize.
- config BR2_TARGET_ROOTFS_UBI_USE_CUSTOM_CONFIG
- 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
- Buildroot also replaces the string "BINARIES_DIR" with the
- value of $(BINARIES_DIR), so that it is possible to reference
- other build artefacts (e.g. to include the kernel in a UBI
- volume).
- config BR2_TARGET_ROOTFS_UBI_CUSTOM_CONFIG_FILE
- string "Configuration file path"
- depends on BR2_TARGET_ROOTFS_UBI_USE_CUSTOM_CONFIG
- help
- Path to the ubinize configuration file.
- config BR2_TARGET_ROOTFS_UBI_OPTS
- string "Additional ubinize options"
- help
- Any additional ubinize options you may want to include.
