Xilinx is introducing Versal, an adaptive compute acceleration platform (ACAP), built on 7nm FinFET process technology. Versal ACAPs combine Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent Engines with leading-edge memory and interfacing technologies to deliver powerful heterogeneous acceleration for any application. The Versal AI Core series has five devices, offering 128 to 400 AI Engines. The series includes dual-core Arm Cortex™-A72 application processors, dual-core Arm Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more than 1,900 DSP engines optimized for high-precision floating point with low latency. The patch is adding necessary infrastructure in place without enabling platform which is done in separate patch. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

This setting is enabled by default. The reserved malloc

memory is initialized with zeros, so first malloc calls

It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN

value, has more than few MiB, e.g. when uses bzip2 or bmp logo.

Then the boot time can be significantly reduced.

When disabling this, please check if malloc calls, maybe

should be replaced by calloc - if one expects zeroed memory.
