CMSIS repo does not support pre-processor defines, hence multiple assembly
files are added for secure/non-secure and floating point tools.
Mbed OS tools support assembly file pre-processing, but the build system
does not support multiple assembly files for each target, hence updating
the assembly files.
1. Patch RTX so irq_cm4f.S files work with no FPU targets
2. Patch RTX so irq_armv8mml.S files to work with and without FPU
2. Patch RTX so irq_armv8mml.S and irq_armv8mbl.S files to work with secure and
non-secure builds
1. Revert "CMSIS/RTX: __FPU_USED to be set based on HW FPU support"
This reverts commit b4f5bed7e75c21927c954a50d40422b81a1de5a0.
2. Revert "CMSIS/RTX: Update Armv8M IAR 8.x assembly files - add END"
This reverts commit b228cd9db0.
3. Revert "CMSIS/RTX: Pre-processor defines used for assembly"
This reverts commit 287121ffdc.
4. Revert "CMSIS/RTX: Patch RTX so irq_cm4f.s files work with no FPU targets"
This reverts commit cc2e0517e1.
In case of ARM compiler, idle and timer thread stack though assigned
to `.bss.os` section since not zero initialized are part of `data` section.
In this commit, we are moving stacks of idle and timer thread to bss
section and thereby saving ROM space.
Main thread in Mbed OS is statically allocated and was not available in call
stack of Keil MDK. The RTX5 kernel requires statically allocated thread
information objects that are placed into a specific section to enable RTOS
thread awareness in Keil MDK. This fix is to keep main thread in specific
section of memory.
Add missing END to the IAR assembly files. In future this commit should be
merged to other assembly file commit, when performing CMSIS update.

The DEVICE_FOO macros are always defined (either 0 or 1).
This patch replaces any instances of a define check on a DEVICE_FOO
macro with value test instead.

Make the option positively named, and as it is a platform config
option make sure it only affects platform code.
HAL functions still remain available even if platform is told not
to use them.
Make the following changes:
-Allow a vector specific ARM MPU driver by defining MBED_MPU_CUSTOM
-Allow ROM address to be configured for ARMv7-M devices by
setting the define MBED_MPU_ROM_END
-Add ROM write protection
-Add new functions and lock
-enable at boot
-disable during flash programming
Enable the MPU as part of the boot sequence and disable it before
starting a new application. Also add reference counted MPU lock and
unlock functions to allow code to execute from ram when necessary.
On platforms using both tickless and the low power ticker wrapper
so much of the background stack is used that it overflows. To
ensure the background thread's stack doesn't overflow increase this
size by 256 bytes when tickless is enabled. Worst case usage
on the NUCLEO_F476RG was recorded at 656 when tickless is
turned on so this increased size should safely prevent overflows.
Only deep sleep when the wakeup time is more than
MBED_CONF_TARGET_DEEP_SLEEP_LATENCY ms in the future.
This ensures that RTOS events are handled at the correct time. Note -
when deep sleep is allow interrupt latency may still be as high as
10ms.
Use write() on current output device instead - this works on the
assumption that write() is safe to call from critical section.
UARTSerial has previously been upgraded to support this, and this also
improves the behaviour when buffered serial is in use - the current
buffered output will be fully flushed before outputting the error
message.
Add a config option for the following values:
MBED_SYS_STATS_ENABLED
MBED_STACK_STATS_ENABLED
MBED_CPU_STATS_ENABLED
MBED_HEAP_STATS_ENABLED
MBED_THREAD_STATS_ENABLED
MBED_CONF_APP_MAIN_STACK_SIZE
MBED_CONF_APP_TIMER_THREAD_STACK_SIZE
MBED_CONF_APP_IDLE_THREAD_STACK_SIZE
MBED_CONF_APP_THREAD_STACK_SIZE
To maintain backwards compatibility inside the RTOS both
APP and RTOS config values can be used.
Refactor the Mbed 5 boot process to make is simpler and more modular.
This is done by breaking the boot sequence into 4 distinct steps -
Target setup, Toolchain setup, RTOS setup and Mbed setup. This patch
also move toolchain specific code into a per toolchain folder to make
it more maintainable.

(cherry picked from commit 287121ffdc)
mbed OS used older RTX4 version and with osThreadDef accepting only 3
parameters, to preserve compatibility we hardcode the 'instances'
parameter to 1.
