Use the SYS_INIT() mechanism to invoke the sys_rand32_init() function in random drivers that require an initializer. Remove all empty sys_rand32_init() instances. The existing explicit sys_rand32_init() function runs immediately after PRE_KERNEL_2 before stack canaries are initialized. In order to get equivalent behaviour with sys_rand32_init() we set SYS_INIT() to initialize the random drivers at the lowest priority of PRE_KERNEL_2.

|
|
*
|
|
* This header file declares prototypes for the kernel's random number generator
|
|
* APIs.
|
|
*
|
|
* Typically, a platform enables the hidden CUSTOM_RANDOM_GENERATOR or
|
|
* (for testing purposes only) enables the TEST_RANDOM_GENERATOR
|
|
* configuration option and provide its own driver that implements
|
|
* sys_rand32_get().
