When packing data into multiple regions using the `.ANY` directive,
the linker can accidentally overfill an area.
This doesn't normally happen because it defaults to
`--any_placement=worst_fit`, which puts data in the region with
most space.
When we prioritise regions with `.ANY1`/`.ANY2`, it may totally fill
an area, then fail to leave enough space for linker-generated veneers.
We've just seen this error with the new K64F linker map.
Adding `--any-contingency` makes it lower priority when a region is
98% full, avoiding this error.
The option should not have any effect on targets with scatter files
without prioritised `.ANY` directives.
-Enable MBED_SPLIT_HEAP for K64F and K66F
-Allow GCC_ARM toolchain to utilize remaining 64K memory area
-Make ARM toolchain to start memory filling from 64K region to leave
more space to bigger 192K region.
When the function `error` is called without ending in a newline
greentea will not display the error. This is because greentea is
performing line buffering.
This patch ensures that all calls to `error` end with a newline. This
is done by adding an additional newline to end end of the string.
Example code exhibiting this problem:
error("This function is not supported.");

In AU/CN/US PHY, RX1 slot frequency is calculated in rx_config().
Since the caller is printing it to log, modify the frequency in
parameter structure so that the correct value will be printed.
Fix device management client compilation on MTB_STM_S2LP

The test case which checks full range cannot be executed at the moment due to a hardware bug in FPGA-Test-Shield.
This test case will be restored when the final version of FPGA-Test-Shield is ready.
In Mbed OS, there are configuration options with Mbed TLS that we
are more comfortable allowing than we do with Mbed TLS on its own.
Add a check-config adjusting script to enable removing or changing
options in check_config.h
For L0/L4/H7/F7/WB targets that have tickless enabled, remove the tickless from
us ticker and the delay ticks as the C++ wrapper layer is being removed
and replaced by the low layer handling.
For now, the few F4 targets with LPTIM are left with previous configuration
as test results are showing a few instabilities not yet understood.
LP TICKER mbed-os wrapper needs to be disabled as it introduces too much latencies.
LP TICKER wrapper has been disabled and we need to managed the HW constraints at low level:
- main HW constraint is that once the comparator has been programmed once,
driver cannot program it again before CMPOK HW flag is set, which takes about 3 30us cycles.
To make it even more complex, the driver also needs to cope with "LP ticker workaround"
See commit:
LP ticker workaround
There is an errata in LPTIM specification that explains that CMP Flag
condition is not an exact match (COUNTER = MATCH) but rather a
comparison (COUNTER >= MATCH).
Also the disable interrupt is more complete now:
- always check sleep manager status and restore it
- remove irq_handler as comparator is always programed and might get called
eventually when LP TICK is restarted
- reset delayed_prog
Also in set_interrupt, make sure interrupt does not fire early.
If needed, we decide to slightly delay the tick to cope with the HW limitation to
make sure it will fire as soon as HW is capable.
Functions are called under critical section as they may be called from
the IRQ handler now, not only from driver layer.
There is an errata in LPTIM specification that explains that CMP Flag
condition is not an exact match (COUNTER = MATCH) but rather a
comparison (COUNTER >= MATCH).
As a consequence the interrupt is firing early than expected when
programing a timestamp after the 0xFFFF wrap-around.
In order to
work-around this issue, we implement the below work-around.
In case timestamp is after the work-around, let's decide to program the
CMP value to 0xFFFF, which is the wrap-around value. There would anyway be
a wake-up at the time of wrap-around to let the OS update the system time.
When the wrap-around interrupt happen, OS will check the current time and
program again the timestamp to the proper value.
