This is based on the original fix by Hervé Poussineau: pc_memory_init
actually takes a memory region for mapping BIOS and extension ROMs. That
equals the PCI memory region if PCI is available, but must be system
memory in the ISA case.

[Originally sent to qemu-kvm list, but I was redirected here]
The Capabilities Pointer is NULL, so this bit shouldn't be set. The state of
this bit doesn't appear to change any behavior on Linux/Windows versions we've
tested, but it does cause Windows' PCI/PCI Express Compliance Test to balk.
I happen to have a physical 82540EM controller, and it also sets the
Capabilities Bit, but it actually has items on the capabilities list to go
with it :)

Wire up the OMAP1 GPIO clock -- this fixes a hw_error() on startup

Convert the omap_intc devices to qdev. This includes adding
a 'revision' property which will be needed for omap3.
The bulk of this patch is the replacement of "s->irq[x][y]"
with "qdev_get_gpio_in(s->ih[x], y)" now that the interrupt
controller exposes its input lines as qdev gpio inputs.
The devices are named "omap-intc" and "omap2-intc", following
the filename and the OMAP2/3 hardware names, although some
internal functions are still named "omap_inth_*".

The previous behaviour was to finish AIOCBs inside curl_aio_readv()
if the data was cached. This caused the following failed assertion
at hw/ide/pci.c:314: bmdma_cmd_writeb
"Assertion `bm->bus->dma->aiocb == ((void *)0)' failed."
By scheduling a QEMUBH and performing the completion inside the
callback, we avoid this problem.

Implement an I/O space index-data register pair as defined by the AHCI
spec, including the corresponding SATA PCI capability and BAR.
This allows real-mode code to access the AHCI registers; real-mode
code cannot address the memory-mapped register space because it is
beyond the first megabyte.

Convert the simple trace backend to glib so that it works under Windows.
We cannot use pthread directly but glib provides portable abstractions.
Also use glib atomics instead of newish gcc builtins which may not be
supported on Windows toolchains.

String arguments are useful for producing human-readable traces without
post-processing (e.g. stderr backend). Although the simple backend
cannot handles strings all others can. Strings should be allowed and
the simple backend can be extended to support them.
