LASI is a built-in multi-I/O chip which supports serial, parallel,
network (Intel i82596 Apricot), sound and other functionalities.
LASI has been used in many HP PARISC machines.
This patch adds the necessary parts to allow Linux and HP-UX to detect
LASI and the network card.

Use class properties facilities to add properties to the class during
device_class_set_props().
qdev_property_add_static() must be adapted as PropertyInfo now
operates with classes (and not instances), so we must
set_default_value() on the ObjectProperty, before calling its init()
method on the object instance.
Also, PropertyInfo.create() is now exclusively used for class
properties. Fortunately, qdev_property_add_static() is only used in
target/arm/cpu.c so far, which doesn't use "link" properties (that
require create()).

First parameter to exynos4210_get_irq() is not the SPI port number,
but the interrupt group number. Interrupt groups are 20 for mdma
and 21 for pdma. Interrupts are not inverted. Controllers support 32
events (pdma) or 31 events (mdma). Events must all be routed to a single
interrupt line. Set other parameters as documented in Exynos4210 datasheet,
section 8 (DMA controller).

It's not what real HW does, implementing which would be overkill [**]
and would require complex cross stack changes (QEMU+firmware) to make
it work.
So considering that SMRAM is owned by MCH, for simplicity (ab)use
reserved Q35 register, which allows QEMU and firmware easily init
and make RAM at SMBASE available only from SMM context.
Patch uses commit (2f295167e0 q35/mch: implement extended TSEG sizes)
for inspiration and uses reserved register in config space at 0x9c
offset [*] to extend q35 pci-host with ability to use 128K at
0x30000 as SMRAM and hide it (like TSEG) from non-SMM context.
Usage:
1: write 0xff in the register
2: if the feature is supported, follow up read from the register
should return 0x01. At this point RAM at 0x30000 is still
available for SMI handler configuration from non-SMM context
3: writing 0x02 in the register, locks SMBASE area, making its contents
available only from SMM context. In non-SMM context, reads return
0xff and writes are ignored. Further writes into the register are
ignored until the system reset.

Provides a blocking call to read a character from the console using
semihosting.chardev, if specified. This takes some careful command
line options to use stdio successfully as the serial ports, monitor
and semihost all want to use stdio. Here's a sample set of command
line options which share stdio between semihost, monitor and serial
ports:
qemu \
-chardev stdio,mux=on,id=stdio0 \
-serial chardev:stdio0 \
-semihosting-config enable=on,chardev=stdio0 \
-mon chardev=stdio0,mode=readline
This creates a chardev hooked to stdio and then connects all of the
subsystems to it. A shorter mechanism would be good to hear about.

Clean-ups: qom-ify serial and remove QDEV_PROP_PTR
Hi,
QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
the pointer points to an Object.
There are a few places where such substitution isn't possible. For
those places, it seems reasonable to use a specific setter method
instead, and keep the user_creatable = false. In other places,
proper usage of qdev or other facilies is the solution.
The serial code wasn't converted to qdev, which makes it a bit more
archaic to deal with. Let's convert it first, so we can more easily
embed it from other devices, and re-export some properties and drop
QDEV_PROP_PTR usage.
