> Stack size has been introduced by commit a69814c815b9 ("arm64: zynqmp:
> Set initrd_high to as high as possible") and commit 085201c246ee ("arm64:
> versal: Set initrd_high to as high as possible")
> to support setting up initrd_high as high as possible.
> The same change should happen for Zynq because the code is moved to xilinx
> common location.
