From 929d9a29e14cbfd890502e6d06b33d37172cacf4 Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak <p.marczak@samsung.com> Date: Wed, 4 Mar 2015 14:01:21 +0100 Subject: [PATCH] exynos: config: enable arch memcpy and arch memset This commit enables the following configs: - CONFIG_USE_ARCH_MEMCPY - CONFIG_USE_ARCH_MEMSET This increases the performance of memcpy/memset and also reduces the boot time. This was tested on Trats2. A quick test with trace. Boot time from start to main_loop() entry: - ~1527ms - before this change (arch memset enabled for .bss clear) - ~1384ms - after this change Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org> Cc: Minkyu Kang <mk7.kang@samsung.com> Cc: Akshay Saraswat <akshay.s@samsung.com> Cc: Simon Glass <sjg@chromium.org> Cc: Sjoerd Simons <sjoerd.simons@collabora.co.uk> --- include/configs/exynos-common.h | 3 +++ 1 file changed, 3 insertions(+) diff --git a/include/configs/exynos-common.h b/include/configs/exynos-common.h index 59676ae61b..87f8db0fba 100644 --- a/include/configs/exynos-common.h +++ b/include/configs/exynos-common.h @@ -24,6 +24,9 @@ #define CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_BOARD_EARLY_INIT_F +#define CONFIG_USE_ARCH_MEMCPY +#define CONFIG_USE_ARCH_MEMSET + /* Keep L2 Cache Disabled */ #define CONFIG_CMD_CACHE -- 2.39.5
