This commit simplifies ticker interrupt set function and handler.
There were issues around the 16 bits timer wrap-around timing as we were
aligning interrupts with wrap-around limits (0xFFFF) and then reading
TIM_MST->CNT again in timer_update_irq_handler which could lead
to crossing case with the wrap-around (TIM_FLAG_UPDATE) case.
Now we're using the 16 lower bits of the timestamp as the reference from
using in set_compare and never changing it. There is also no need to set
comparator again in timer_update_irq_handler. This is more robust and
also more efficient.
Move to a single more reliable implementation of us_ticker_read()
There were historically 2 versions of us_ticker_read() implementation.
The one removed here was not reliable because us_ticker_read() can be
called in interrupt context which means that TIM_MST->CNT would have
wrapped around while SlaveCounter is not yet updated. So there is a need
to check the TIM_FLAG_UPDATE inside this function, which was not done in
the implementation that is removed here.
This patch split the Case class in two entities: Case and case_t. case_t contains the test case data structure while Case provide the interface to the test case. Unlike the class Case, case _t is a POD and can be instantiated at compile time and put in the constant data section (in ROM).
The Specification class has also been modified to accept arrays of case_t.
Silence deprecation warnings in the config store C and C++ files. This
removes warnings that not relevant to applications. Note - using
these deprecated functions still gives an error outside of these files.
Move the metrics mutex into the ifdef MBED_STACK_STATS_ENABLED since
it is not used ouside of it. This fixes the warning:
[Warning] greentea_metrics.cpp@37,28: 'mutex' defined but not used [-Wunused-variable]
As reported in issue #4214, there are seen issues seen first on
NUCLEO_F103RB in case of successive Reads of 1 byte at a time.
This issue is due to a wrong state management in the end of read sequence.
Also F1 i2c driver was not fully aligned to others, which is updated here.
There were still side effects, in particular on I2C master slave test,
when setting by default the Pin Speed for F1 family. So for F1 family,
let's do it only in case of Output which is the only case where this
actually applies on this family.
Move memory allocation to be done at a different location. Currently allocated
in a function that is called from the interrupt handler.

uVisor doesn't set the PSP of the target thread. The RTOS sets the PSP
of the target thread from the target thread's TCB. However, when
interrupts of higher priority than PendSV happen between the call to
uVisor to switch boxes, and the RTOS setting PSP, the uVisor vIRQ
interrupt handler will attempt to use an invalid PSP (the PSP from
before the box and thread switch). This leads to a crash. Make box and
thread switching atomic by disabling interrupts immediately before the
box switching until immediately after the new PSP is set.
In class MBRBlockDevice the tole32 function had used union member
names u32 and u8. The introduction of REALTEK_RTL8195AM cauesd a
conflict with type names in basic_types given they're aliased as
macros to uint32_t and uint8_t respectively.
There is an easy default implementation of spi_master_block_write that
just calls spi_master_write in a loop, so the default implementation
of spi_master_block_write has been added to all targets.
