Seems something is broken with the serial support in 3.9 and later. Tested openrisc-3.9 branch form Jonas repository and current mainline as of yesterday with same symptom. The exact same kernel config & dts works fine on 3.8 and earlier.
Running in or1ksim works fine, but on two different FPGA boards the serial port becomes silent once fully configured. The early bootconsole do work, and boot continues fine up to userspace if keep_bootcon is used and serial0 is disabled in the dts (i.e. disabling the full serial driver, only using simple polled bootcon driver). To keep things simple the tested kernel config & dts is the same as for or1ksim except for clock frequency.
