This commit implements a SPI mode which will offer better performance
thanks to usage of Lower Layer API which use fewer registers access,
at the cost of lower robustness (no error management).
This provides the correct binary semaphore behaviour that was expected
by the equeue layer, removes concerns around semaphore overflow, and
reduces the number of spurious wakeups which may save a bit of power.
This also fixes some issues we were seeing around the RTX 5 changes
to semaphore behaviour.
This patch updates CMSDK_CM3DS.h to remove the
DMA peripheral memory map and defines, as
that peripheral is not present in the system.
In addition, some define names where updated
concerning rtc. RTC_api was updated accordingly.
This patch also updates SMM_MPS2 to align defines and
comments.

This patch implements pin_function and gpio_set
with some fixes in the PinNames.
The patch also updates the serial and spi
drivers to use the pin_function.

cmsis 5 does not include it but as mbed 2 requires this, we will bring this file
back. This brings back few other dependencies, that we add only for cortex-a.
Once cortex-a gets cmsis5 and rtx2 support it will be updated.
At some point the "mount" parameter for "f_mount" was name "force". This
led to a bit of confusion that ended with the default mount function
never calling block device init.
This is fine, since the block device can be manually initialized, but
a better user experience is where the filesystem initializes the block
device for the user.
This is backwards compatible due to the repeatability of the block
device init functions.
Following
Merge pull request #4063 from LMESTM/17q2_L4_bootloader
the NUCLEO_L476RG binairies could not boot anymore.
The change done in #4063 was derived from work on NUCLEO_L429ZI target
which supports uvisor. The VECTORS defintiion is introduced as part of
uvisor support and requires further changes in ld file which were missing.
As uvisor is not considered yet, we remove VECTORS for now and will
introduce only when needed.
A message of "Failed to close socket" was always being printed, not
just when the socket failed to close. This patch fixes this in
addition to a simplifying the call to a thread safe printf.
Remove HAL_Init and related code from SystemInit and move it to
mbed_sdk_init. The function SystemInit is called early in the boot
sequence before RAM is initialized or the VTOR is setup, so it should
not be used to perform the HAL initialization.
This fixes crashes due the vector table being used before it has been
relocated.
