Change the handling of port F0h writes and FPU exceptions to implement IGNNE.
The implementation mixes a bit what the chipset and processor do in real
hardware, but the effect is the same as what happens with actual FERR#
and IGNNE# pins: writing to port F0h asserts IGNNE# in addition to lowering
FP_IRQ; while clearing the SE bit in the FPU status word deasserts IGNNE#.

Move it out of pc.c since it is strictly tied to TCG. This is
almost exclusively code movement, the next patch will implement
IGNNE.

There are three page size in qemu:
real host page size
host page size
target page size
All of them have dedicate variable to represent. For the last two, we
use the same form in the whole qemu project, while for the first one we
use two forms: qemu_real_host_page_size and getpagesize().
qemu_real_host_page_size is defined to be a replacement of
getpagesize(), so let it serve the role.
[Note] Not fully tested for some arch or device.

QEMU does not wait for completed I/O requests, assuming that the guest
driver will reset the device before calling unrealize(). This does not
happen on Windows, and QEMU crashes in virtio_notify(), getting the
result of a completed I/O request on hot-unplugged device.

write_secondary_boot() is used in SMP configurations where the
CPU address space might not be the main System Bus.
The rom_add_blob_fixed_as() function allow us to specify an
address space. Use it to write each boot blob in the corresponding
CPU address space.

This file creates the BCM2836/BCM2837 blocks.
The biggest differences with the BCM2838 we are going to add, are
the base addresses of the interrupt controller and the peripherals.
Add these addresses in the BCM283XInfo structure to make this
block more modular. Remove the MCORE_OFFSET offset as it is
not useful and rather confusing.

Switch the milkymist-sysctl code away from bottom-half based
ptimers to the new transaction-based ptimer API. This just requires
adding begin/commit calls around the various places that modify the
ptimer state, and using the new ptimer_init() function to create the
timer.

virtio_device_stop_ioeventfd() has not been used since commit
310837de6c ("virtio: introduce
grab/release_ioeventfd to fix vhost") in 2016.
Nowadays ioeventfd is stopped implicitly by the virtio transport when
lifecycle events such as the VM pausing or device unplug occur.

This patch implements basic support for the packed virtqueue. Compare
the split virtqueue which has three rings, packed virtqueue only have
one which is supposed to have better cache utilization and more
hardware friendly.
Please refer virtio specification for more information.

The function virtio_del_queue was not called at unrealize() callback.
This was detected due to add an allocated element on the vq introduce
in future commits (used_elems) and running address sanitizer memory

All these devices do not contain any target-specific. While most
of them are arch-specific, they are shared between different
targets of the same arch family (ARM and AArch64, MIPS32/MIPS64,
endianess, ...).
Put them into common-obj-y to compile them once for all targets.

In the slavio timer device, the ptimer TimerContext::timer is
always created by slavio_timer_init(), so there's no need to
check it for NULL; remove the single unneeded NULL check.
This will be useful to avoid compiler/Coverity errors when
a subsequent change adds a use of t->timer before the location
we currently do the NULL check.
