Freescale KSDK2 gpio_object.h pulled in Freescale libraries to inline
some GPIO operations.
The resulting namespace pollution (status_t) doesn't seem to be worth
the function call overhead. Hopefully making the base address array
non-automatic will offset that loss.
mbed TLS requires an entropy source, and this provides support for one through
the K64F RNG.
The macro MBEDTLS_ENTROPY_HARDWARE_ALT also added to target.json to enable use
of the entropy collector by mbed TLS.
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.
Continuation of patch: 07b841b08f
Change-Id: Iab0341847130f86e16500fd85024b6a87525fe14
Added CAN API support for NUCLEO_L476RG target.
"stm32l476xx.h" file was changed to avoid compilation errors.
Change-Id: Ifadf7048f6c72c0311ec915e47ce2190460ede68
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.
Following cube update, there has been changes in cube HAL that impact
the serial_api.c layer. The global state has been moved to separate
global/tx and rx states, so we can now differentiate both.
The NRF51 doesn't have a systick. When the MCU doesn't have a systick, the
HAL has to export several functions which will be use by the kernel to
manage the tick:
* os_tick_init provides the initialization function for the alternative
hardware timer.
* os_tick_val returns the current value of the alternative hardware timer.
* os_tick_ovf returns the overflow flag of the alternative hardware timer.
* os_tick_irqack is an interrupt acknowledge function that is called to
confirm the alternative hardware timer interrupt.
The HAL should also call OS_Tick_Handler needs to be called as the
hardware timer interrupt function.
In the case of the NRF51, two RTCs are available:
* RTC0: reserved for soft device
* RTC1: used by us_ticker.
RTC1 is a 4 channels timers, channel 0 is used for us_ticker, and
in this port channel 1 is used for tick generation.
Implementation notes:
* RTC1_IRQHandler: has to be written in assembly otherwise a stack
overflow will occur because the function OS_Tick_Handler never
returns. This function is called when RTC1 channel IRQ is triggered.
* tick generation has been optimised for a tick with a duration of
1000us.
* us_ticker can still be compiled and used without RTX enabled.
