Well one problem seems to be the rx condition,
        ... if ((s->ier & UART_IER_RDI) && (s->lsr & UART_LSR_DR))
is not enough to trigger an irq, yet still causes the following
conditions not to be checked anymore at all.

The logic of Zilog makes channel B the first device and channel A the

With this patch applied ide drives (when attached to a pci adapter) can
be created via -device, like this:

  -drive if=none,id=mydisk,file=/path/to/disk.img
  -device ide-drive,drive=mydisk,bus=ide.0,unit=0

Note that creating a master on ide1 doesn't work that way.  That is a
side effect of qemu creating a cdrom automagically even if you don't
ask for it.

This allows the ide bus being initialized without drives attached
and the drives being attached and initialization later on as
separate step.

Like pci_create_simple() but doesn't call qdev_init(), so one can
set properties before initializing the device.

The serial ports should be present even if associated with a null device
as some firmware wants to initialize them.

When creating null devices, there is no way to ensure the unicity of
the labels. Bail out with an error message instead.

Changes:
  * added isa bus, hooked up to the system bus. Not sure this is correct,
    but 'info pci' lists lists no pci-isa bridge in the machine ...).
  * switches the default cpu to one which actually works.

Recent versions of the Linux kernel will not preempt CPU-intensive
tasks unless the clock used by sched_clock() works.  On -M versatilepb
that's the 24MHz timer in the system controller.  It's a very simple
timer, so implement it.

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235,
f40d7537,
96555a96 and
3990d09a but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.
