What does the 8250 have to recommend it over just providing the PL011?
As I mentioned, it will just work for anything that expects the serial port to be ttyS0 as on x86 rather than ttyAMA0.
This doesn't seem very compelling to me. Either userspace should just be fixed or the kernel should implement a namespace for serial ports which doesn't randomly change just because the particular h/w driver doing the implementation is different. We shouldn't be papering over other peoples' problems in the VM spec IMHO.
Indeed.
This is already causing us trouble in other contexts. Please have a look at this patch for a solution:
