Reduce the boot time of Odroid X2/U3 by disabling the memset at malloc init.
This was tested on Odroid X2. A quick test with checking gpio pin state using the oscilloscope. Boot time from start to bootcmd (change gpio state by memory write command): - ~228ms - before this change (arch memset enabled for .bss clear) - ~100ms - after this change Signed-off-by: Przemyslaw Marczak <p.marc...@samsung.com> Reviewed-by: Simon Glass <s...@chromium.org> --- Changes V3 - update commit head Changes V4 - odroid_defconfig: remove CONFIG_EXPERT - odroid_defconfig: disable CONFIG_SYS_MALLOC_INIT_DO_ZEROING Changes v5 - update disabled config name to CONFIG_SYS_MALLOC_CLEAR_ON_INIT Changes v6: - fix merge conflict with master --- configs/odroid_defconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configs/odroid_defconfig b/configs/odroid_defconfig index 816a3fa..cfb29e0 100644 --- a/configs/odroid_defconfig +++ b/configs/odroid_defconfig @@ -2,6 +2,6 @@ CONFIG_ARM=y CONFIG_ARCH_EXYNOS=y CONFIG_TARGET_ODROID=y CONFIG_OF_CONTROL=y -CONFIG_DEFAULT_DEVICE_TREE="exynos4412-odroid" CONFIG_DM_I2C=y CONFIG_DM_I2C_COMPAT=y +# CONFIG_SYS_MALLOC_CLEAR_ON_INIT is not set -- 1.9.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
