prompt "Generate UBI Image "
help
Build ubi formated image(s) for the root file system and an
optional data partition. UBI is faster and robuster than JFFS2,
we recommend strongly the usage of UBI if you want a file
system for raw flash devices. The image(s) can be directly
written to e.g. an mtd partition on a raw flash devices.

prompt "Create root volume "
help
Create a root volume with the content of root.ubifs. You will
most probably want to activate this option is essential since
otherwise the final ubi image will not contain a root file
system.
if IMAGE_UBI_ROOT_VOL
config IMAGE_UBI_ROOT_VOL_SIZE
string
prompt "root volume size"
default "<invalid>"
help
Give the root volume size here. You can use size unit like
"KiB" or "MiB".
The volume size must be greater than than the actual ubifs
file. Further the sum of all volumes in an UBI image should
be slightly smaller than the mtd device, to wich the image
will be flashed. The spare place is supposed to be used for
Jounal and other UBI header informations. We recommend a
ratio between spare place and the actual size of the mtd
partion at about 10% or higher. It is OK to define a big
amount of spare place. The UBI System will scan for available
space during first boot and expand the volume to the maximal
usable size after reserving internally used blocks.
An example: Our UBI image is supposed to contain a single "root"
volume. The mtd partition, onto which we will flash the UBI
image has a size of 32MiB. Our actual rootfs.ubifs has a size
of 16MiB. Than we should define our root volume size between
16MiB and 29MiB. We decide for 25MiB. During the boot process
the UBI system detects a mtd partiton of 32MiB. After reserving
2MiB for internal use it will expand our volume automatically to
30MiB.
