The documentation for the icount documentation has some minor issues:
* in a couple of places it says "sleep=on|off" when in the context of the
sentence it means specifically "sleep=on"
* the synopsis line for the documentation has drifted out of sync
with the synopsis line in the DEF() macro (used for "-help" output)
* the synopsis line in the DEF() macro is missing a "][" between
the sleep= part and the rr= part
* the synopsis line doesn't indicate that rrsnapshot is an optional
part of the rr=mode,rrfile=filename subgrouping
* we don't document that sleep=on can't be used with shift=auto
or align=on
* the rr option description had some minor grammar and formatting
errors and was a bit terse
* in commit f1f4b57e88 in 2015 the documentation of the sleep=
suboption got added between the two paragraphs defining general
behaviour of the icount option. This meant that the second
paragraph talking about the behaviour of "this option" reads as
if it's talking about sleep=on, when it's really describing -icount
as a whole. The paragraph is better moved back up to above the
sleep= section.
* the summary text displayed in "-help" output didn't mention
the record-and-replay part

The q800 board code connects both of the IRQ outputs of the ESCC
to the same pic[3] qemu_irq. Connecting two qemu_irqs outputs directly
to the same input is not valid as it produces subtly wrong behaviour
(for instance if both the IRQ lines are high, and then one goes
low, the PIC input will see this as a high-to-low transition
even though the second IRQ line should still be holding it high).
This kind of wiring needs an explicitly created OR gate; add one.
