Can you or Lada provide more details as to exactly what is not working - what driver to be precise 8250 or dw-8250. And where exactly the failure shows up. I want to understand this more Noam told me off list that he has no issues with both big endian ARC + 8250 in systemc model or silicon. -Vineet
