Yes, that may sound stupid, but when dealing with 20+ year old hardware, you really do not want to change any runtime behaviour. To that end, these cleanups are things I spotted when doing the freescale errata addition and figured I could deal with in a way that was "inert" to the serial and 8250 users at large. I've stared at the changes to convince myself that they really don't change the compiled code (and even cheated by diffing the assembly), and I've tested with serial console on a headless turd that is ~10 years old and not seen any sort of regressions. But please report if you see any problems in this patch set. I intend on testing on a few !x86 arch in the next few days myself.
