Fix the following build warning seen with both GCC and ARM_CC
[Warning] btle.cpp@115,0: #177-D: variable "clockConfiguration" was declared but never referenced
Add Cypress HCI driver implementation in TARGET_Cypress directory.
Update targets.json to enable CORDIO stack for Cypress PSoC 6 boards
with CYW43XXX radios with compatible HCI driver implementation:
CYW4343W and CYW43012.
TARGET_CYW4343X Bluetooth HCI driver is specific to STM32 targets
derived from USI_WM_BN_BM_22. Move the driver implementation to
TARGET_STM folder to not interfere with Cypress implementation at
TARGET_Cypress/TARGET_CYW43XXX/HCIDriver.cpp that is enabled for
PSoC 6 targets which also include the CYW4343X label.
The relationnal operators were targeting the base class which defines an implicit constructor to an integral value. This is wrong as it allows SafeEnum instances to be compared against integers.
The fix is simple: define relationnal operators for the derived class. The derived class is known as it is passed as a template parameter of the base class.
For extra safety the SafeEnum constructor is now explicit and protected.
Previously, the CryptoToolbox was allocated once as part of the security manager.
This was inneficient memory wise as it is only use to prepare key at initialization
and when we need to compute shared keys.
This was also inneficient power consumption wise as the Crypto cell was kept enabled even
when it wasn't used.
This fix creates a CryptoToolbox whenever it is needed and release it once it has fulfilled its
purpose. Note that CryptoToolbox allocation happens on the heap as mbed tls data structure are huge
and there's an high risk of crushing the stack.
the own_oob and peer_oob flags were not being set to 1 even though
an OOB pairing request was in progress, which therefore prevented
OOB data from being passed down to the softdevice during a OOB
pairing operation, thus causing the OOB pairing process to fail.
