This fixes problem we have seen with rtos_idle_loop. The symbols
was not resolved as order played a role in this case. Remove circular
dependencies member, as it should not be required anymore.
This causing a warning in the rt_cmsis.c, as they use preprocessor
to redefine a type. A fix is to move the macro above, as it should not
change anything else. This should be removed, and use a cast, however I am
not fully familiar why they do this macro trick.
2 new macros were introduced to capture changes in the kernel. We used toolchains/__init__
script to capture those, which is not in the sync with actual sources. This fix introduces
those macros in the source, rather than a script.
We will further eliminate those macros to be used outside of RTX kernel (c++ API).
This enables the stack info methods to be supported for Cortex-M
targets. The rt_TypeDef required one small change - rename new structure
member as this is a reserved keyword in C++.
We need to ask for tid everytime we need to use tcb, do not expose internal
RTX details, we keep it within Thread.cpp file.
Cherry pick commit d587474778 -
"RTX: Support stacks larger than 64k"
This allows the latest version of the RTOS to run mbed client over
ethernet without crashing.
Thread - stack methods are not available for now, as tcb pointer was removed from
internal structure. To obtain it, we could get it from the kernel, but this should be
reconsidered. Either RTOS should provide it, or these methods will become deprecated.
Changes to the original kernel:
Cortex-M requires to define __CMSIS_OS_RTX, and __MBED_CMSIS_RTOS_CM. The macro __MBED_CMSIS_RTOS_CM
is mbed specific macro, to track changes to the kernel. This should keep us aware what has changed. For instance,
one breaking change was thread adding instances variable, which were not in mbed. This can be find as
it's protected via __MBED_CMSIS_RTOS_CM ifdef.
```
// added for mbed compatibility
// original RTX code
```
Startup for toolchains - mbed defines own stack pointer (set_main_stack()), therefore it should be called in the startup.
IAR added low level init calls and dynamic intialization to the IAR startup. All defined in RTX_CM_lib.h.
The timer thread has task id 0x01, main task 0x02. There are exception for main task not to check for
overflows. This is mbed specific, was reapplied from mbed code base.
IAR fixed SVC calls, this fix had to be reapplied (repo mbed PR 736 for more information).
There are 28 filter banks which are shared between CAN1 and CAN2. By default
they are divided in half:
* CAN1 -> 0 ... 13
* CAN2 -> 14 ... 27
that's why we need to decied which filter number has to be chosen.

For some reason STACKHEAP block was placed in SRAM2 section which lead to
*Error[Lp011]: section placement failed - unable to allocate space for sections/
block* error. This patch modifies the STM32L4 linker script and places STACKHEAP
into SRAM1 section which was previously unused.

Some flags are only C specific, causes problems when there's .S file in the workspace.
For instance, -Ox is only C flag, causes a project to fail with "unrecognized option"
Introducing the prescaler management allows a wider period range support,
from about 65ms before now up to about 32s. We're also introducing
asserts in case the period or prescaler is truncated as the HW registers
are 16 bits large.
