Kernel Address Space Layout Randomization (KASLR) is a hardening feature that aims to make it more difficult to take advantage of known exploits in the kernel, by placing kernel data structures at a random address at each boot.The bootloader supports randomizing the virtual address at which the kernel image is loaded. The bootloader must provide entropy by passing a random u64 value in the /chosen/kaslr-seed device tree node. When we run "kaslrseed" command from U-Boot, the bootloader will genarate the kaslr-seed and update the /chosen/kaslr-seed DT property.
