Gabriel Valcazar 604dcbc20f ccimx6ul/ccmp1: compress recovery UBIFS image using zlib to reduce its size
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.

OpenEmbedded/Yocto BSP layer for Digi's ConnectCore platforms
=============================================================

This layer provides support for Digi's ConnnecCore platforms for use
with OpenEmbedded and/or Yocto.

This layer depends on:

git://git.yoctoproject.org/poky.git
git://git.openembedded.org/meta-openembedded.git
git://git.yoctoproject.org/meta-freescale.git

Digi's license agreements
-------------------------

All software is covered by Digi's general EULA and Digi's Open Source
EULA. To have the right to use the software in your images you need to
read and accept both EULAs at the DIGI_EULA and DIGI_OPEN_EULA files.

NXP Semiconductors' software license agreement
----------------------------------------------

Some platforms depends on libraries and packages that are covered by
NXP Semiconductors' EULA. To have the right to use those binaries in
your images you need to read and accept the EULA file in meta-freescale
Yocto layer.

Support
-------

This layer is provided 'as is' with no guarantee. However, some support
may be available from tech.support@digi.com
