At this moment layerscape images are ext4 only. It causes problem with save changes durring sysupgrade and make "firstboot" and failsafe mode useless. This patch changes sd-card images to squashfs + f2fs combined images. To make place, for saving config, kernel space ar now ext4 partition with fit kernel. This method of image generation is similar to rest of OpenWrt sd-card targets.

DEVICE_COMPAT_MESSAGE := DTB was added to sysupgrade. Image format is different. \
|
|
To use sysupgrade You need to change firmware partition in bootargs to "49m@0xf00000(firmware)" and saveenv. \
|
|
After that, You can use "sysupgrade -F".

It is required to flash the entire sd-card again and manually copy config.
