fire_interrupt function should be used for events in the past. As we have now
64bit timestamp, we can figure out what is in the past, and ask a target to invoke
an interrupt immediately. The previous attemps in the target HAL tickers were not ideal, as it can wrap around easily (16 or 32 bit counters). This new
functionality should solve this problem.
set_interrupt for tickers in HAL code should not handle anything but the next match interrupt. If it was in the past is handled by the upper layer.
It is possible that we are setting next event to the close future, so once it is set it is already in the past. Therefore we add a check after set interrupt to verify it is in future.
If it is not, we fire interrupt immediately. This results in
two events - first one immediate, correct one. The second one might be scheduled in far future (almost entire ticker range),
that should be discarded.
The specification for the fire_interrupts are:
- should set pending bit for the ticker interrupt (as soon as possible),
the event we are scheduling is already in the past, and we do not want to skip
any events
- no arguments are provided, neither return value, not needed
- ticker should be initialized prior calling this function (no need to check if it is already initialized)
All our targets provide this new functionality, removing old misleading if (timestamp is in the past) checks.
This patch updates CMSDK_CM3DS.h to remove the
DMA peripheral memory map and defines, as
that peripheral is not present in the system.
In addition, some define names where updated
concerning rtc. RTC_api was updated accordingly.
This patch also updates SMM_MPS2 to align defines and
comments.

- Creates new target in targets.json
- Creates device specific files under ARM_SSG/CM3DS_MPS2 directory
- Driver layer files under CM3DS_MPS2 are based on Beid target
- Device specific files under CM3DS_MPS2/device are based on CMSIS_5 and Beetle

Restore cmsis_nvic (cmsis_nvic.c and cmsis_nvic.h) files for the
implementations which use a mechanism other than the VTOR to set
interrupts. These are vendor specific and were done for M0 devices
which do not have a VTOR.
Note - There were two cmsis_nvic files which did not use the VTOR that
which not restored in this patch. This is because these targets were
not M0 devices and could use the new unified implementation instead.
These files are:
targets\TARGET_ARM_SSG\TARGET_MPS2\TARGET_MPS2_M0P\device\cmsis_nvic.c
targets\TARGET_ONSEMI\TARGET_NCS36510\device\cmsis_nvic.c
Note - cmsis_nvic.c and cmsis_nvic.h were initial removed in
(and restored from) the commit:
b97ffe8fdc -
"CMSIS5: Replace target defined NVIC_Set/GetVector with CMSIS implementation"
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.
Affected boards: NRF51_DK, NRF52_DK, Beetle. This change is temporary and
will be overwritten by RTX update. It's necessary for the boards to pass
updated tests.
Add sleep/deepsleep functions to platform layer which are replacing HAL
functions with the same name, rename existing symbols in HAL layer
to hal_sleep/hal_deepsleep. This way sleep functions
are always available, even if target doesn't implement them, which makes
the code using sleep clearer. It also enables us to make decision on in
which builds (debug/release) the sleep will be enabled.
This patch updates DualTimer_DisableInterrupt to
disable the interrupt timers individually.
In addition, it updates lp_ticker accordingly.
