2f9db77ea8 arm: Move M-profile RAS register block into its own device
Currently we implement the RAS register block within the NVIC device.
It isn't really very tightly coupled with the NVIC proper, so instead
move it out into a sysbus device of its own and have the top level
ARMv7M container create it and map it into memory at the right
address.

9516034d05 Some qemu updates for IPMI and I2C
Move some ADC file to where they belong and move some sensors to a
 sensor directory, since with new BMCs coming in lots of different
 sensors should be coming in.  Keep from cluttering things up.
 
 Add support for I2C PMBus devices.
 
 Replace the confusing and error-prone i2c_send_recv and i2c_transfer with
 specific send and receive functions.  Several errors have already been
 made with these, avoid any new errors.
 
 Fix the watchdog_expired field in the IPMI watchdog, it's not a bool,
 it's a u8.  After a vmstate transfer, the new value could be wrong.

38f2cfbbc3 hw/arm: Add basic power management to raspi.
This is just enough to make reboot and poweroff work. Works for
linux, u-boot, and the arm trusted firmware. Not tested, but should
work for plan9, and bare-metal/hobby OSes, since they seem to generally
do what linux does for reset.

The watchdog timer functionality is not yet implemented.

380a37e498 hw/misc: Add NPCM7XX MFT Module
This patch implements Multi Function Timer (MFT) module for NPCM7XX.
This module is mainly used to configure PWM fans. It has just enough
functionality to make the PWM fan kernel module work.

The module takes two input, the max_rpm of a fan (modifiable via QMP)
and duty cycle (a GPIO from the PWM module.) The actual measured RPM
is equal to max_rpm * duty_cycle / NPCM7XX_PWM_MAX_DUTY. The RPM is
measured as a counter compared to a prescaled input clock. The kernel
driver reads this counter and report to user space.

1e943c586a hw/misc: Add a PWM module for NPCM7XX
The PWM module is part of NPCM7XX module. Each NPCM7XX module has two
identical PWM modules. Each module contains 4 PWM entries. Each PWM has
two outputs: frequency and duty_cycle. Both are computed using inputs
from software side.

This module does not model detail pulse signals since it is expensive.
It also does not model interrupts and watchdogs that are dependant on
the detail models. The interfaces for these are left in the module so
that anyone in need for these functionalities can implement on their
own.

The user can read the duty cycle and frequency using qom-get command.

fc14176ba2 hw/arm/raspi: add a skeleton implementation of the CPRMAN
The BCM2835 CPRMAN is the clock manager of the SoC. It is composed of a
main oscillator, and several sub-components (PLLs, multiplexers, ...) to
generate the BCM2835 clock tree.

This commit adds a skeleton of the CPRMAN, with a dummy register
read/write implementation. It embeds the main oscillator (xosc) from
which all the clocks will be derived.

326ccfe240 hw/misc: Add npcm7xx random number generator
The RNG module returns a byte of randomness when the Data Valid bit is
set.

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
data is available.

A qtest featuring some simple randomness tests is included.

c1b2982627 hw/misc/led: Add a LED device
Add a LED device which can be connected to a GPIO output.
They can also be dimmed with PWM devices. For now we do
not implement the dimmed mode, but in preparation of a
future implementation, we start using the LED intensity.

LEDs are limited to a fixed set of colors.

e331f79eb8 hw/misc: Add NPCM7xx Clock Controller device model
Enough functionality to boot the Linux kernel has been implemented. This
includes:

  - Correct power-on reset values so the various clock rates can be
    accurately calculated.
  - Clock enables stick around when written.

In addition, a best effort attempt to implement SECCNT and CNTR25M was
made even though I don't think the kernel needs them.

e5a7ba8788 hw/misc: Add NPCM7xx System Global Control Registers device model
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.

dccb92b5ca hw/misc/sbsa_ec : Add an embedded controller for sbsa-ref
A difference between sbsa platform and the virt platform is PSCI is
handled by ARM-TF in the sbsa platform. This means that the PSCI code
there needs to communicate some of the platform power changes down
to the qemu code for things like shutdown/reset control.

Space has been left to extend the EC if we find other use cases in
future where ARM-TF and qemu need to communicate.
