Hi Przemyslaw, > 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> > > --- > Changes V3, V4, V5 > - none > --- > 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 59676ae..87f8db0 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 > Acked-by: Lukasz Majewski <l.majewski@samsung.com>
