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>
