* Added mechanism enabling CPU to
enter WFI mode when the OS is
in idle, what results in large
power consumption reduction.
* Added mechanism to switch SDRAM to
self-refresh mode before entering
WFI, what resulted in further power
consumption reduction.
To allow the automation of gathering logs and swapping out OS images during tests a MSC reboot
endpoint was added. Together with a change to ecoboot, this allows the sending of a "reboot to
MSC" command. The deivce will then reboot and enter MSC mode.
* Adding document describing how to use logger
* Adjusting logs to follow a new guide
* Change order in log header:
line number is now before function name
- Sentinel locks the frequency when pressing buttons and the encoder.
- The "user activity" sentinel will be properly managed by the system
(CpuGovernor) just like other sentinels.
- Adding information about active sentinels in the power management
statistics logs
Multiple fixes of clock switching related
stability issues:
* added RC oscillator hysteresis as in NXP example;
* changed DCDC converter config;
* configure PLL2 to be able to run on any CPU
frequency level;
* added switching to 1.275V (overdrive) voltage
when applying any clock change above 12MHz as
well as LDO or bandgap switching, as done in
Mbed OS' lpm.c for RT1050;
* changed BMCR AXI queues weighs for SDRAM
in JLink scripts to disable operations
reordering, as it is known to cause data
integrity issues;
* extracted some code to separate files;
* smaller or bigger code cleanups.
Remove mechanics enabling to perform reboot
to MSC mode by sending request to one of the
endpoints via serial port, as it is not
implemented in bootloader and may potentially
be unsafe.
Redesign of backup and restore endpoints in the
service-desktop to delegate responsibility for
execution of the actual backup and restore process
onto the Updater.
Gets data from freertos and prints on frequency change depending
if it's important. Gathering is not costly, printing is though.
For less intrusive checks I would rather disable names gathering
as in worst case scenario it hangs rtos context switching till
thread id is found.
Split module-utils into smaller components for better dependency
management. Fix many dependencies throughout the project.

Extends reboot reason codes after reboot to updater
to detect updater command requests: Update, FactoryReset
and the Recovery.

Because update procedure it is splitted to the two stages
downloading and update throught separate binary we need
to pass ecoboot special flag to request reboot to updater
bin after update procedure.
This patch adds this functionality to the PureOS.

In order to synchronize the Low Power mode, the services were
immediately informed about the frequency change,
so that they can update their resources (e.g. PWM filling)
and services may request the maximum CPU frequency in order
to perform a task (e.g. screen redraw, telephone conversation)
Till now there was no clear way to register hanlder for message in
Service, with this approach one can register function/lambda handler
for Message which encurages handling messages in functions rather than
in hudge switch cases.
With aproach like this our Messages resembe something between Command
and State pattern. In state pattern `Message` would be `Event` send,
whereas Service would be `Context`.
