From 3c1c68cc0385b9e703f785b9744bd9b07733cb48 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Tue, 25 Mar 2014 10:58:19 +0100 Subject: lib: rand: introduce new configs: CONFIG_LIB_RAND and CONFIG_LIB_HW_RAND 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) Signed-off-by: Przemyslaw Marczak Cc: Michael Walle Cc: Tom Rini Cc: Masahiro Yamada --- include/common.h | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'include/common.h') diff --git a/include/common.h b/include/common.h index 5c9bd08..072a1e1 100644 --- a/include/common.h +++ b/include/common.h @@ -835,9 +835,7 @@ char * strmhz(char *buf, unsigned long hz); #include /* lib/rand.c */ -#if defined(CONFIG_RANDOM_MACADDR) || \ - defined(CONFIG_BOOTP_RANDOM_DELAY) || \ - defined(CONFIG_CMD_LINK_LOCAL) +#if defined(CONFIG_LIB_RAND) || defined(CONFIG_LIB_HW_RAND) #define RAND_MAX -1U void srand(unsigned int seed); unsigned int rand(void); -- cgit v1.1
