COM9 on a Vortex86DX is now working in Linux 3.3.8 but it requires more than a simple serial driver patch. I'm not entirely sure how to go about creating a proper patch for the changes I have made. My serial driver writes to the South Bridge, but it's a quick hack using outl() calls to the right addresses. Should I use a proper PCI function call? I also modified the x86 io port mappings in /arch/x86/kernel/setup.c. Do I either add #ifdef-ery to setup.c, or create a new entry in arch/x86/kernel/cpu/ and do my different io mappings there?
