Re: [U-Boot] [PATCH v5 5/7] trats2: defconfig: disable memset at malloc init

Hi Przemyslaw,

Reduce the boot time of Trats2 by disabling the memset at malloc init.

This was tested on Trats2. A quick test with trace. Boot time from start to main_loop() entry:

• ~464ms - before this change (arch memset enabled for .bss clear)
• ~341ms - after this change
