Hi, list
Does anyone here familiar to the serial 8250 driver?
I enabled two uart ports in my board definition, but the ports doesn't
appear after I loaded the kernel (3.4.19). I discovered, it failed at
the UART port auto configuration stage, the exact function is
autoconfig(...) in drivers/tty/serial/8250.c.
Sounds like you're using some kind of buggy UART IP... sharing which one
might help people identify the problem, if they have seen it before.
