Re: [U-Boot] [U-Boot, v6, 01/10] 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

Applied to u-boot/master, thanks!
