Before, rtx calls would hard fault in critical sections when an svc
instruction was attempted with interrupts disabled.
Required changes:
- Added check for CPSR I bit in cortex A rtx
- Added check for PRIMASK in cortex M rtx
- Modified critical sections in cortex M rtx to be recursive
(already recursive in cortex A)
*Changes*
- Parallel export
- mbed-os tests added
- specified release version (default to 5)
- default tests AND targets dependent on specified release version
This addresses the issue where building tests via test.py always triggered
a clean build. This is because the mbed_config.h file was being deleted from
the shared OS build to ensure that the correct config was always being
used. However, this contanstly triggered a rebuild of the OS since the
config file was not present.
Due to the shared build, having multiple app configurations that could
override the OS settings is not possible. For this reason, we now ignore
app config files unless explicitly set via the command line option
'--app-config'. Though there will now be two mbed_config.h files in the
include path of the build, it shouldn't matter since the contents will be
the same.
As per reference manual, closing communication for master receiver
with repeated start requires, after reading second last data byte
(after second last RxNE event):
-Clearing ACK bit (same as non repeated start case)
-Set START bit (instead of STOP bit in non repeated start case)
This is valid for I2C_FIRST_FRAME and I2C_NEXT_FRAME conditions
Disintegrate global RTX target config. Move per-target fragment
to mbed_rtx.h under each vendor's directory.
One mbed_rtx.h is defined for each vendor at this moment, however,
the granularity of mbed_rtx.h can be per-chip, or per-board
if necessary.

1. Use function pointer for interrupt handler, this should reduce the code-size
for applications that do not use this driver
2. Fix the wait for initialization of the SD card
3. Fix SDHC driver support for non-word aligned accesses
4. Remove some redundant code & assert function calls.
5. Updated various comments

Following discussion on:
it seems now clear that the transfer API is meant to be used either
with only Rx, or only Tx or Rx and Tx with the same lenth.
Therefore we're removing support of transfers of Rx and Tx with different
lenghts - this makes porting to HAL more direct and simpler.
This commit is highly derived from an existing work from salkinium.
It adds SPI ASYNC support to STM32 F4 devices. This required a small
rework of the structure to have SYNCH and ASYNCH co-exist.
