New configs: - CONFIG_LIB_RAND - to enable implementation of rand library in lib/rand.c - CONFIG_LIB_HW_RAND - to enable hardware based implementations of lib rand
Other changes: - add CONFIG_LIB_RAND to boards configs which needs rand() - put only one rand.o dependency in lib/Makefile
CONFIG_LIB_HW_RAND should be defined for drivers which implements rand library (declared in include/common.h): - void srand(unsigned int seed) - unsigned int rand(void) - unsigned int rand_r(unsigned int *seedp)
