This compression method has a better compression ratio than the default (lzo),
but the (de)compression speed is slower, leading to slower read/write speeds.
However, the recovery partition only gets accessed in specific use cases such
as software updates and partition encryption, and it contains an initramfs. The
UBIFS will only be read at boot time to load its elements, but once the
initramfs is loaded in RAM, there are no more read/write operations to the
UBIFS during runtime, so the speed penalty is minimal.
Take advantage of the improved compression ratio to reduce the size of the
recovery image. On the ccimx6ul, the size is reduced by 248 KiB.
