Hello all, I didn't follow the entire discussion, but I might have similar problems on the AU1100 SoC. The AU1100 also has 16550 style serial ports. The serial console doesn't work even though I specify console=/dev/ttyS0 on the kernel command line. Once a getty is started, the serial port is active and working fine.
