The NPCM7xx chips have multiple GPIO controllers that are mostly
identical except for some minor differences like the reset values of
some registers. Each controller controls up to 32 pins.
Each individual pin is modeled as a pair of unnamed GPIOs -- one for
emitting the actual pin state, and one for driving the pin externally.
Like the nRF51 GPIO controller, a gpio level may be negative, which
means the pin is not driven, or floating.

The NPCM730 and NPCM750 chips have a single USB host port shared between
a USB 2.0 EHCI host controller and a USB 1.1 OHCI host controller. This
adds support for both of them.
Testing notes:
* With -device usb-kbd, qemu will automatically insert a full-speed
hub, and the keyboard becomes controlled by the OHCI controller.
* With -device usb-kbd,bus=usb-bus.0,port=1, the keyboard is directly
attached to the port without any hubs, and the device becomes
controlled by the EHCI controller since it's high speed capable.
* With -device usb-kbd,bus=usb-bus.0,port=1,usb_version=1, the
keyboard is directly attached to the port, but it only advertises
itself as full-speed capable, so it becomes controlled by the OHCI
controller.
In all cases, the keyboard device enumerates correctly.

The RNG module returns a byte of randomness when the Data Valid bit is

This implementation ignores the prescaler setting, and loads a new value
into RNGD every time RNGCS is read while the RNG is enabled and random

The watchdog is part of NPCM7XX's timer module. Its behavior is

When enabled, the watchdog issues an interrupt signal after a pre-set

We expected the 'version' ID to match the board processor ID,
but this is not always true (for example boards with revision
id 0xa02042/0xa22042 are Raspberry Pi 2 with a BCM2837 SoC).
This was not important because we were not modelling them, but
since the recent refactor now allow to model these boards, it
is safer to check the processor id directly. Remove the version
check.

Using class_data pointer to create a MachineClass is not
the recommended way anymore. The correct way is to open-code

We can not use TYPE_RASPI_MACHINE::class_base_init() because
it is called *before* each machine class_init(), therefore the
board_rev field is not populated. We have to manually call

When debugging QEMU it is often useful to put a breakpoint on the
error_setg_internal method impl.
Unfortunately the object_property_add / object_class_property_add
methods call object_property_find / object_class_property_find methods
to check if a property exists already before adding the new property.
As a result there are a huge number of calls to error_setg_internal
on startup of most QEMU commands, making it very painful to set a
breakpoint on this method.
Most callers of object_find_property and object_class_find_property,
however, pass in a NULL for the Error parameter. This simplifies the
methods to remove the Error parameter entirely, and then adds some
new wrapper methods that are able to raise an Error when needed.

Some machines don't have much differences a part from the flash model
being used. Introduce new machine properties to change them from the
command line.
For instance, to start the ast2500-evb machine with a different FMC
chip and a 64M SPI chip, use :
-M ast2500-evb,fmc-model=mx25l25635e,spi-model=mx66u51235f

When booting directly into a kernel, bypassing the boot loader, the CPU and
UART clocks are not set up correctly. This makes the system appear very
slow, and causes the initrd boot test to fail when optimization is off.
The UART clock must run at 24 MHz. The default 25 MHz reference clock
cannot achieve this, so switch to PLL2/2 @ 480 MHz, which works
perfectly with the default /20 divider.
The CPU clock should run at 800 MHz, so switch it to PLL1/2. PLL1 runs
at 800 MHz by default, so we need to double the feedback divider as well
to make it run at 1600 MHz (so PLL1/2 runs at 800 MHz).
We don't bother checking for PLL lock because we know our emulated PLLs
lock instantly.

This adds two new machines, both supported by OpenBMC:
- npcm750-evb: Nuvoton NPCM750 Evaluation Board.
- quanta-gsj: A board with a NPCM730 chip.
They rely on the NPCM7xx SoC device to do the heavy lifting. They are
almost completely identical at the moment, apart from the SoC type,
which currently only changes the reset contents of one register
(GCR.MDLR), but they might grow apart a bit more as more functionality
is added.
Both machines can boot the Linux kernel into /bin/sh.

The Nuvoton NPCM7xx SoC family are used to implement Baseboard
Management Controllers in servers. While the family includes four SoCs,
this patch implements limited support for two of them: NPCM730 (targeted
for Data Center applications) and NPCM750 (targeted for Enterprise
applications).
This patch includes little more than the bare minimum needed to boot a
Linux kernel built with NPCM7xx support in direct-kernel mode:
- Two Cortex-A9 CPU cores with built-in periperhals.
- Global Configuration Registers.
- Clock Management.
- 3 Timer Modules with 5 timers each.
- 4 serial ports.
The chips themselves have a lot more features, some of which will be
added to the model at a later stage.

Implement a device model for the System Global Control Registers in the
NPCM730 and NPCM750 BMC SoCs.
This is primarily used to enable SMP boot (the boot ROM spins reading
the SCRPAD register) and DDR memory initialization; other registers are
best effort for now.
The reset values of the MDLR and PWRON registers are determined by the
SoC variant (730 vs 750) and board straps respectively.
