If anyone has any objections, please let me know. ------------------ From: Arnaud Patard commit aaa10eb1d0034eccc096f583fe308f0921617598 upstream. The rules used to make 8250_pci "ignore" the PCH uarts are lacking pci subids entries, preventing it to match and thus is breaking serial port support for theses systems. This has been tested on a nanoETXexpress-TT, which has a specifici uart clock.
