Porting Android 5.0 to Allwinner A20 (mount_all /fstab.chipname problem)

[Patryk Czarnota]

Hi guys! (and girls maybe? )

I'm trying to port newest android version to cubieboard 2 and I have a little problem at this moment. If anyone have experience with porting android 4.4 and higher it will be great if you could help me.

I have problem with mounting partitions with fstab.sunXi file by init program. If anyone could share a logs with loglevel=7 from init from android 4.4 or higher (from any allwinner chip)?
I've got that error message:
fs_mgr: __mount(source=/dev/block/by-name/system,target=/system,type=ext4)=-1
fs_mgr: Failed to mount an un-encryptable or wiped partition on/dev/block/by-name/system at /system options: (null) error: No such file or directory

Can anyone tell me from where got "/by-name" folder? What a program create that folder? I'm looking for any information about fstab.sunXi file and mounting by that file too.
