On M2351, some spaces like SYS/CLK are hard-wired to secure and cannot change.
To access these spaces from non-secure world, we must provide platform-specific NSC
functions. With TFM introduced, we must synchronize NSC calls into TFM to keep TFM
in sync instead of straight NSC calls. To achieve this goal, we go with the following
approach:
1. Like PSA APIs, enforce locked entry through tfm_ns_lock_dispatch().
2. Run platform-specific secure functions in default secure partition, in which SYS/CLK
spaces have been configured to be accessible.
Default NS lock functions use mutex to guarantee serialization into secure world.
But this mechanism doesn't support pre-rtos and interrupt-disabled.
This commit changes these functions to weak so that platform can override them to provide another mechanism.
This approach is just what TF-M repository is adopting.

Replace the thread used in the test case teardown with a Ticker to allow
testing with the bare metal profile. This Ticker is used to prevent the
watchdog from resetting the device during the final greentea
communication.
- Earlier some variables were public even though used only internally
- Also refactored variables to the end of class definitions
- Removed duplicate _property_array from CellularDevice
- Changed _impl methods as protected
The size stated in the struct header was 0xB0, however
the actual size(including the header) is 0xAC. Changed the
len value in the header, to avoid memory corruption.
Raised in #12171
Rather than wait 10ms before breaking the other thread, and expecting at
least one event to have been run, wait for one event to be run, then
break.
Should avoid some spurious failures that have been seen.
Mbed OS was carrying this directory for a long time. The main reason was
to enable users to benefit from some form of USB stack. Now when there
is proper implementation of USB stack in Mbed I think it's time for
unsupported directory to go. If any other functionality present in this
directory will be needed it'll need to be introduced in Mbed OS
properly.
All targets must implement soft_- and hard_power_on/off() functions which are practically same what onboard_modem_api offered.
These were seen as a duplicate features and therefore we removed this.
All targets involved have been updated to reflect the changes
On IAR, configure heap to 1KiB at a minimum and expandable, dependent on available SRAM. This requires IAR 8.x.
Support targets:
- NUMAKER_PFM_NUC472 w/ and w/o XRAM
- NUMAKER_PFM_M453
- NUMAKER_PFM_M487/NUMAKER_IOT_M487
- NUMAKER_IOT_M263A
- NUMAKER_M252KG
