Currently, the ubifs-in-ubi-image ("UBI image" thereafter) filesystem
is half an option of the ubifs filesystem, half a filesystem on its
own: the config options are options of the ubifs filesystem, but the
.mk code is in a separate .mk and registers a real filesystem.
Make it a full filesystem on its own, in its own directory tree.

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.

Tells ubinize that the flash supports sub-pages and the sub-page

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
