/**

|
|
* @brief Random number generator header file
|
|
*
|
|
* This header file declares prototypes for the kernel's random number generator
|
|
* APIs.
|
|
*
|
|
* Typically, a platform enables the hidden CUSTOM_RANDOM_GENERATOR
|
|
* configuration option and provide its own driver that implements both
|
|
* sys_rand32_init() and sys_rand32_get(). If it does not do this, then for
|
|
* projects that require random numbers, the project must either implement
|
|
* those routines, or (for testing purposes only) enable the
|
|
* TEST_RANDOM_GENERATOR configuration option.
