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
