The ext4l driver requires the filesystem framework (FS) and rbtree library (RBTREE) to build correctly. Add the first as an explicit dependency and 'select' the second, to prevent build failures when ext4l is enabled.

This provides support for reading images from the ext4 filesystem,
|
|
using code ported from Linux. This is mutually exclusive with
|
|
FS_EXT4 (the existing U-Boot ext4 implementation).
|
|
|
|
This requires 64-bit LBA support for proper block counting.

help
|
|
This enables journal (jbd2) support for ext4 filesystems. The
|
|
journal provides crash-consistency by logging metadata changes
|
|
before committing them to the filesystem.
|
|
|
|
If unsure, say Y.

Enable debug and informational messages from the ext4l filesystem.
|
|
This includes mount messages and other ext4_msg() output.
|

|
|
If unsure, say N.
