- __heap_size__ was used to allocate a fixed size region for the heap in
RW_IRAM1
- __user_setup_stackheap in sys.cpp uses Image$$RW_IRAM1$$ZI$$Limit as the
start of the heap, which leaves the fixed size region unused
If you don't specify the start address of a section explicitly, that
section can end up at different addresses depending on its alignment. If
the alignment of a section is not explicitly set, it inherits it from
the element with the highest alignment inside that section.
Since the uVisor code is in the .text section, and it *must* end up at a
known location, we set the start address of .text to 0x410, which is the
value that the uVisor binary expects.

This fix is a solution for issue #816 when having two separate IRQ handlers
in Timers (UPDATE Irq and OutputCompare Irq). The update priority needs to
be higher to avoid undefined behaviours.

This is backwards-compatible with unsupported targets.
If an application is compiled using the K64F target without uVisor
(UVISOR_PRESENT not set or set to 0) then uvisor_init() will just be an
empty function that immediately returns.
This commit includes all sections that are just added to the linker
script. These changes are backwards-compatible, meaning that they will
not affect the existing code.
Targets that do not support uVisor will leave those sections empty.
Due to directory structure change, modification in e93878078 was made wrong
after rebasing the code.
This reverts commit e938780788 and updates path
to the correct file.
Note:
Current value of TIM_MST->CNT is read in interrupt context only.
This avoids master timer overflow without SlaveCounter update.

Added CAN API support for DISCO_L476VG target.
*stm32l476xx.h* file was changed to avoid compilation errors.
NOTE: MBED_29 or MBED_30 cannot be tested on this platform because CAN pins are
soldered to USB, GYRO and others.

With this change, the heap section occupy the whole space from the end of
the bss section to the start of the stack section instead of taking a
fixed size in RAM.
This change allows applications to make a more efficient use of the RAM
available and allows application to be compiled if the space between end
of bss and start of stack is less than 2048 bytes.
The KSDK2 update restricts static data to the first 64K of RAM.
This breaks some applications which require more than 64K of
static data. This patch moves the static data sections
(bss and data) into the second ram region which is 192K.

- Resetting in LPCXpresso IDE did not reset the LCD controller which
sometimes could cause strange behaviour
- The ROM_LAT bit in the MATRIXARB register must be set in order to
prevent a HardFault when debugging
- The change of compiler in LPCXpresso IDE to ARM launchpad GCC5 was
causing build errors due to multiply defined timeval symbol.
- The exporters for LPCXpresso IDE did not set the FPU_PRESENT define
for assembler, only for c/c++. This caused very strange behaviour
in the RTOS code (e.g. timeouts no longer working, context switches
failing etc.)
