Yes.. this was because of rootfstype which forced ext3 fs driver to be
used instead of trying all available fs drivers (e.g. ext2, ext3, ext4.. etc)

Right.. but without gta04-init in SHR kernel it was trying to mount real
rootfs (with qtmoko) just after flashing SHR kernel instead of qtmoko
gta04-init mounts it correctly, because is's trying fs in order ext4,
ext3, btrfs.. so my boot.txt patch just makes u-boot doing the same.

has right uImage and today new images should be there, but yesterday I
got some issues with systemd on om-gta04, it seems like vfat partition
gets broken very soon and systemd switches to emergency mode when it
cannot mount it (or something like that).
