From 3c1c68cc0385b9e703f785b9744bd9b07733cb48 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Tue, 25 Mar 2014 10:58:19 +0100 Subject: [PATCH] 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 +--- include/configs/MERGERBOX.h | 1 + include/configs/MVBC_P.h | 1 + include/configs/MVBLM7.h | 1 + include/configs/MVSMR.h | 1 + include/configs/a3m071.h | 1 + include/configs/bfin_adi_common.h | 1 + include/configs/lsxl.h | 1 + include/configs/sacsng.h | 1 + lib/Makefile | 4 +--- 10 files changed, 10 insertions(+), 6 deletions(-) diff --git a/include/common.h b/include/common.h index 5c9bd08f45..072a1e1615 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); diff --git a/include/configs/MERGERBOX.h b/include/configs/MERGERBOX.h index 930699ba6d..19ea3167af 100644 --- a/include/configs/MERGERBOX.h +++ b/include/configs/MERGERBOX.h @@ -312,6 +312,7 @@ #define CONFIG_BOOTP_NTPSERVER #define CONFIG_BOOTP_RANDOM_DELAY #define CONFIG_BOOTP_SEND_HOSTNAME +#define CONFIG_LIB_RAND /* * Command line configuration. diff --git a/include/configs/MVBC_P.h b/include/configs/MVBC_P.h index 99e4e9051f..036396c781 100644 --- a/include/configs/MVBC_P.h +++ b/include/configs/MVBC_P.h @@ -104,6 +104,7 @@ #define CONFIG_BOOTP_NTPSERVER #define CONFIG_BOOTP_RANDOM_DELAY #define CONFIG_BOOTP_SEND_HOSTNAME +#define CONFIG_LIB_RAND /* * Autoboot diff --git a/include/configs/MVBLM7.h b/include/configs/MVBLM7.h index 30af691c5a..27c2fa011d 100644 --- a/include/configs/MVBLM7.h +++ b/include/configs/MVBLM7.h @@ -227,6 +227,7 @@ #define CONFIG_BOOTP_NTPSERVER #define CONFIG_BOOTP_RANDOM_DELAY #define CONFIG_BOOTP_SEND_HOSTNAME +#define CONFIG_LIB_RAND /* USB */ #define CONFIG_SYS_USB_HOST diff --git a/include/configs/MVSMR.h b/include/configs/MVSMR.h index bb565b602e..ad15506fad 100644 --- a/include/configs/MVSMR.h +++ b/include/configs/MVSMR.h @@ -92,6 +92,7 @@ #define CONFIG_BOOTP_SEND_HOSTNAME #define CONFIG_BOOTP_SUBNETMASK #define CONFIG_BOOTP_VENDOREX +#define CONFIG_LIB_RAND /* * Autoboot diff --git a/include/configs/a3m071.h b/include/configs/a3m071.h index 1e65cd1465..205adfd8ce 100644 --- a/include/configs/a3m071.h +++ b/include/configs/a3m071.h @@ -58,6 +58,7 @@ #define CONFIG_BOOTP_SERVERIP #define CONFIG_NET_RETRY_COUNT 3 #define CONFIG_CMD_LINK_LOCAL +#define CONFIG_LIB_RAND #define CONFIG_NETCONSOLE #define CONFIG_SYS_CONSOLE_IS_IN_ENV #define CONFIG_CMD_PING diff --git a/include/configs/bfin_adi_common.h b/include/configs/bfin_adi_common.h index 08ccce0b9a..ea9acf69d1 100644 --- a/include/configs/bfin_adi_common.h +++ b/include/configs/bfin_adi_common.h @@ -17,6 +17,7 @@ # define CONFIG_BOOTP_DNS # define CONFIG_BOOTP_NTPSERVER # define CONFIG_BOOTP_RANDOM_DELAY +# define CONFIG_LIB_RAND # define CONFIG_KEEP_SERVERADDR # define CONFIG_CMD_DNS # define CONFIG_CMD_PING diff --git a/include/configs/lsxl.h b/include/configs/lsxl.h index 2ae8a2700d..96a889fe87 100644 --- a/include/configs/lsxl.h +++ b/include/configs/lsxl.h @@ -37,6 +37,7 @@ #define CONFIG_SHOW_BOOT_PROGRESS #define CONFIG_RANDOM_MACADDR +#define CONFIG_LIB_RAND #define CONFIG_KIRKWOOD_GPIO #define CONFIG_OF_LIBFDT diff --git a/include/configs/sacsng.h b/include/configs/sacsng.h index 0a694fb1be..b5064ab37c 100644 --- a/include/configs/sacsng.h +++ b/include/configs/sacsng.h @@ -457,6 +457,7 @@ #endif /* CONFIG_BOOT_ROOT_NFS */ #define CONFIG_BOOTP_RANDOM_DELAY /* Randomize the BOOTP retry delay */ +#define CONFIG_LIB_RAND /* * BOOTP options diff --git a/lib/Makefile b/lib/Makefile index 8814ff9671..ae8086529e 100644 --- a/lib/Makefile +++ b/lib/Makefile @@ -62,8 +62,6 @@ obj-y += time.o obj-$(CONFIG_TRACE) += trace.o obj-$(CONFIG_BOOTP_PXE) += uuid.o obj-y += vsprintf.o -obj-$(CONFIG_RANDOM_MACADDR) += rand.o -obj-$(CONFIG_BOOTP_RANDOM_DELAY) += rand.o -obj-$(CONFIG_CMD_LINK_LOCAL) += rand.o +obj-$(CONFIG_LIB_RAND) += rand.o subdir-ccflags-$(CONFIG_CC_OPTIMIZE_LIBS_FOR_SPEED) += -O2 -- 2.39.5
