You have more than one problem.  The first one is the console
configuration in your Linux kernel.  Re-check how your serial p[orts
are configured, and which one is ttyS0 or ttyS1.  Also check your
device tree to include correct descriptions of the serial ports.

The second issue is with y our root file system.  It seems it cannot
run the init process, so check this, too.  Note that in many cases it
is easier to bing up a system using a root file system mounted over
NFS - then you can easily trace all file system accesses using a
simple network sniffer, and you can see immediately where the system
stops working correctly.
