Well control has passed to the linux kernel, so you need to start
diagnosing Linux - U-Boot works fine now ;)

Is the "console" setting correct?  I.e. are you connected to ttyS2?
Does U-Boot pass the correct machine number (check with bdinfo) for the
kernel you use?

If you can reset the board at this time, you can try to inspect the
kernel logbuffer for output which Linux produced but which never reached
your serial connection:
