If you don't specify then the kernel picks one. udev can then create the right /dev/ttyPS1/2/3 nodes itself. If you have devtmpfs enabled then devtmpfs is a virtual file system which will just have the nodes in at as specified by the drivers. It eliminates all the hard work maintaining device nodes/ranges in user space. > The only reason we didn't just use ttyS0 was that it's not a 8250 really If you'd attempted to use ttyS0 you would indeed have been told to change it > and > since we have are an FPGA people can add real 8250s in soft logic and > then > the system would get confusing. and that's exactly why !
