The HACE (Hash and Crypto Engine) is a device that offloads MD5, SHA1,
SHA2, RSA and other cryptographic algorithms.
This initial model implements a subset of the device's functionality;
currently only MD5/SHA hashing, and on the ast2600's scatter gather
engine.

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.

The SSE-300 has a new register block CPU<N>_PWRCTRL. There is one
instance of this per CPU in the system (so just one for the SSE-300),
and as well as the usual CIDR/PIDR ID registers it has just one
register, CPUPWRCFG. This register allows the guest to configure
behaviour of the system in power-down and deep-sleep states. Since
QEMU does not model those, we make the register a dummy
reads-as-written implementation.

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.

The reset values of the MDLR and PWRON registers are determined by the
