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.
* Make memory sections configurable in linker files
* Dynamically determine vector location in flash for NVIC relocation
* Advertise bootloader support in targets.json
When using ARM Compiler 5, the RTX config hard-coded the heap and stack
sizes to specific values. This prevented the RTX HAL from dynamically
allocating unused memory as heap space.
Specifically, the HEAP_START define prevents this logic in RTX_CM_lib.h
from activating. The rest of the defines are also set in that header,
and should be removed from here.
* Using PinName as bitfield doesn't work without warnings, since NC
needs all 32 bits to be represented.
* lp_ticker should not be freed when interrupt is disabled, since this
will kill the timebase.
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.
If one of the CC channel pins is enabled, `pwmout_all_inactive` it
means a channel is active so it should return `true`.
This commit also contains some cleanup in `pwm_init`.
* Update i2c driver to tackle multiple I2C object instances on different pins
* Update pinmap to enable the extra peripherals of EFx32xG12 over EFx32xG1
Due to limitation in the mbed website backend (board names need to be <= 19 characters), we are shortening the CLI target names from THUNDERBOARD to TB.

As asked by @0xc0170 in PR #3934, we won't be using device_has for indicating RF/Crypto features any longer. RF config options moved to the SL_RAIL lib.json, crypto config options will come with mbedTLS integration.
* Off by one error in the linker scripts reserved one word too little for the vector table
* Re-apply uvisor changes to emlib. To allow uvisor to run, we should make accesses to the romtable through uvisor's secure read gateway
* Copypasta in target name (EFM32PG12, not EFR32PG12)
* Copypasta in the pin definitions (thanks @akselsm)
* Forgot to update PortName for extra ports on MG/PG12
With the RTOS, the STACK_SIZE specified here is unrelated to the stack
size available for the main thread (that runs pre_main). Save memory by
reducing the stack size to a more reasonable amount.
On uVisor, HEAP_SIZE is both a minimum available and maximum available
heap size. The heap can't grow beyond the end of the heap into the
neighboring stack. On all uVisor-supported platforms, guarantee at least
0x6000 bytes of heap space. This increases the portability of uVisor
applications as the memory available for legacy heap allocations is
guaranteed. This helps to avoid out of memory errors on platforms that
were previously guaranteeing less memory.
A copy paste error snuck into the uVisor related updates to the EFM32GG
linker script. Fix the error by replacing "m_data" with "RAM".
Fixes: 89641bc7e0 "uVisor: Update K64F and EFM32GG linker scripts"
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 commit improves consistency between different platforms' linker
scripts. In particular, we use "__UVISOR_SRAM_START" instead of
"__UVISOR_BSS_START" as the uVisor BSS sections might be outside of the
SRAM (for example, when using a tightly-coupled memory).
