Both STM32F0xx and STM32F1xx are using a 16-bit timer as a internal ticker
but the mBed ticker needs a 32-bit timer implementation, so the upper part
of that 32-bit timer is being calculated in software.
Software bug has been fixed where continous HIGH/LOW voltage levels
could be observerd for 65ms due to 16-bit timer overflow.
Now current value of TIM_MST->CNT is stored in cnt_val and is
updated in interrupt context only. This avoids master timer
overflow without SlaveCounter update.
This fix is only for platforms which already implements a 16-bit timer:

(long commit message ahead. Sorry about that, it can't be helped.)
This commit changs targets definition from Python to JSON format, as
part of the configuration mechanism implementation. There is a new file
under workspace_tools/ called "targets.json" which contains the target
definitions. "targets.py" remains, but becomes a wrapper on top of
"targets.json", with the same interface as before. This has the
advantage of not requiring code changes outside "targets.py".
Most of the JSON definitions of targets were automatically generated by a
script (available upon request since it doesn't make a lot of sense to
include it here), only those targets that had more than one parent in
the Python implementation were converted by hand. The target definitions
should be pretty self-explanatory. A number of things are different in
the JSON implementation (this is just a summary, check docs/mbed_targets.md
(also part of this PR) for a more complete description):
- "program_cycle_s" is now a value (as opposed to a function in the
Python implementation), since it only returned a number in all the
Python target implementations. The main definition that actually contains
some code (in class "Target") remains in target.py
- array values in "macros" and "extra_labels" can be modified
dynamically. Values can be added using "macros_add" and
"extra_labels_add" or removed using "macros_remove" and
"extra_labels_remove". This mechanism is available for all attributes
with a list type, but it's currently enabled only for "macros" and
"extra_labels" to keep things simple.
- "init_hooks"/"binary_hook" are now implemented in terms of a single
JSON key valled "post_binary_hook". The corresponding code is also in
"targets.py", under the various TargetCode classes (see for example
LPC4088Code in targets.py).
Just like in the Python implementation, a target can inherit from zero,
one or more targets. The resolution order for the target's attributes
follows the one used by the Python code (I used
http://makina-corpus.com/blog/metier/2014/python-tutorial-understanding-python-mro-class-search-path
as a reference for the implementation of resolution order).
This is obviously a very dangerous commit, since it affects all targets.
I tested compilation for a number of targets (K64F, LPC1768, NRF51822)
but there's definitely a lot more to be done in terms of testing.
I also tried to test in a different way: I wrote a script that imports the
old (Python) and the new (JSON) implementations and verifies that the
attributes in the old implementations exist and have the same values
in the new implementations (it also verifies that the attribute
resolution order is the same in the two implementations). If you're
interested, the script is here:
https://gist.github.com/bogdanm/c9d8cf34214109a4b9079befed6b3c0c
And the results of running the script are below (note that the script
outputs only the target names that were found to be problematic):

The reasons for the above output are subtle and related to the
extremely weird way in which we defined target data in the Python
implementation: we used both class attributes and instance attributes.
This can complicate resolution order quite a bit and those two levels
don't exist in JSON: there's only one attribute type (equivalent to
Python's instance attributes). To make that work, I had to change the
inheritance order of the above targets (that use multiple inheritance)
which in turn changed the order of some macros and extra_labels (and of
course the resolution order). No harm done: the values are the same,
only their ordering is different. I don't believe this causes any
problems for 'extra_labels' and 'macros'.
This method of testing has its limitations though; in particular, it
can't test the hooks. I'm opened to ideas about how to test this better,
but I think that we need to remember that this commit might break some
targets and keep an eye out for "weird errors" in the future.
we changed the sequence of ROM section to "<ro code> <ro data>" when compiled with the IAR.
When the ROM area is large, PC could not jump properly in the program area.
The other development environment of this sequence ("ro code, ro data").

In this PR, rtx has updated, the macro into the code were changed.
However, by this macro, the process of task generation in Cortex-A9 can no longer be run.
So, we solve the task generation problem by changing the macro into Tread.cpp again.
