Certain instances of the TPM are missing some registers, updated
TPM driver handles this variation. This issue was discovered when
running the PWMOUT tests using the ci-test-shield

1. Start function: Issue repeat start when bus is busy
2. Byte write function: Do not call SDK function as this does
not work for some of the Kinetis device
3. Byte read function: Do not call SDK function as this would
issue a START and STOP signal which is not required for
I2C byte functions

I2C3 clock define was missing. I2C3 is connected to the Arduino
connector which is used by the ci-test shield

Delta calculation from lp_ticker_set_interrupt() function:
delta_us = timestamp > now_us ? timestamp - now_us : (uint32_t)((uint64_t)timestamp + 0xFFFFFFFF - now_us);
Lets assume that timestam == now_us.
Expected delta value should be 0 and in this current version is 0xFFFFFFFF.
The following condition:
timestamp > now_us
should have the following form:
timestamp >= now_us
Additionally modified us ticker driver to provide the same logic.
If NVIC_NUM_VECTORS is larger than the space allocated by the vector
table in ram (__ram_vector_table_size__) then the call to mbed_cpy_nvic
during boot will corrupt valid data, which can lead to a crash. This
patch fixes the declared number of vectors on the KL27Z, KL43Z and
KL82Z to fix this crash.
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.
When initializing the RTC on Kinetis devices, handle the case where
the time overflow interrupt is pending and the case where the time
alarm flag is pending. These flags persist across reset and if not
handled will cause a crash when powering up the low power ticker.
This problem manifested as a lp_ticker test failure on the K22F and
K64F on CI only when running a nightly. This problem has been present
but was made obvious by PR #4094 which configures all tickers to
interrupt at least every MBED_TICKER_INTERRUPT_TIMESTAMP_MAX_DELTA
(~31 minutes). This caused the RTC alarm to fire 31 minutes after the lp_ticker
or lp_timeout test and caused the next run of the lp_ticker test to
crash on boot.
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.

Check in flash algos for the K64F, KL46Z, F429, F439 and Odin board
and enable these features accordingly in targets.json. This
implementation uses flash algo blob that are generated via scripts.
The K64F and KL46Z were generated directly from packs, while the
KL46Z, F429, F439 and odin were generated from code checked into
the FlashAlgo repo.
Add MBED_APP_START and MBED_APP_SIZE to the K64F's linker script
so the start and size of an image can be specified. This allows the
ROM to be split into a bootloader region and an application region.
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.
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).
