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.marc...@samsung.com> Cc: Minkyu Kang <mk7.k...@samsung.com> Cc: Akshay Saraswat <aksha...@samsung.com> Cc: Simon Glass <s...@chromium.org> Cc: Sjoerd Simons <sjoerd.sim...@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 1f3ee55..5c14c40 100644 --- a/include/configs/exynos-common.h +++ b/include/configs/exynos-common.h @@ -30,6 +30,9 @@ #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 -- 1.9.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
