* 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.
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.
Added mechanism that stores address of last
executed instruction before RTWDOG timeout
to enable some basic debugging in such cases,
as such resets do not create crashdumps and
leave no information in logs.
Next part of Harmony random resets fixes:
* added RC OSC startup delay as in newest lpm.c;
* changed order of clock source, oscillator and
LDO switching;
* removed connecting internal DCDC load resistor,
as it is only required to speed up converter
startup after it was turned off completely;
* changed DCDC operation mode to continuous
conduction;
* set low VDD_SOC_IN voltage back to 950mV as
suggested in RM.
* added switching DCDC converter mode to
discontinuous conduction for two lowest CPU
clock frequencies, as using CCM mode resulted
in very high current consumption that would
shorten Harmony's life on battery
significantly.
* Fix of the issue that manifested after
running MuditaOS on Harmony via JLink,
which resulted in OS freezing when
trying to set time in normally booted
(via the bootloader) device.
* Minor RTC code cleanup.
* Partial T6 JLink script cleanup.
There is the possibility of hanging
the MCU due to a power glitch
if the voltage drops to 2.8V
and the system wants to use some
peripherals like the eink or the backlight.
To prevent this situation brownout
detection has been enabled
which monitors the 1.1V and 2.5V
LDO regulators. If the voltage
will drop to the trigger voltages
then the interrupt is invoked.
The interrupt checks the source
of the interrupt and then reset
the MCU using WDOG_B pin
which is connected to the main power source.
After restarting, the MCU checks
the voltage. If it is too low
the system enters SNVS mode.
Added atexit functionality. All global destructors and functions
registered with atexit() should be called at program exit.
It was possbile to reuse original newlib implementation with
MALLOC_PROVIDED flag set.
Made sure logger destructructor is called as last one.
Due to mudita OS legacy, it was not possible to simply fix dependencies
in global objectes and hence there are neither global objects
destructors nor functions registered with atexit() called when exit()
is called.
Possibly it will be changed later.
Add support for Reboot and Power off for the
_platform_exit code.
Add _platform_exit mode handle

The start address of the OS image adjusted to comply with HAB
Secure Boot. Proper SNVS initialization performed at system startup.
SNVS drivers updated to most recent version. Image signing can be
performed as a part of build process. See doc/secure_boot.md for
more info.
Integrate the CrashCatcher library in order to store phone state after
a fault occurs. The dumps are stored in the CrashCatcher hex format and
can be debugged using the CrashDebug stub built for x86_64 via the
'debug_crash_dump.sh' script.
Audio devices are created in the audio subsystem and it is not possible
to send a device to bt service upon creation.
Introduce hookable audio device factory to allow sharing bluetooth
audio device. Move audio devices from bsp to audio allowing removal of
unwanted bsp -> audio dependency.
Remove Bluetooth proxy device which turned out to be a dead end.

Improve workers destroying by replacing sudden death with a gentle close
request.
Make (De)Init static - when creating second instance of a codec there
was a situation when destructing one instance was causing first one to
stop working, because they share common hardware resources.
Change SDRAM configuration from 4M for code and 13M (which is invalid)
for heaps to 6M for code and 10M for heaps.
Usermem heap's size has been decreased to 9M.
Use heap start symbol __sdram_cached_start for MPU configuration instead
of using magic values which are easy to miss when they are need to be
changed.
This change is required to be able to fit in libphonenumber.
