Tim Harvey 00afd1ec82 Add fdt_kaslrseed function to add kaslr-seed to chosen node ... If RANDOMIZE_BASE is enabled in the Linux kernel instructing it to randomize the virtual address at which the kernel image is loaded, it expects entropy to be provided by the bootloader by populating /chosen/kaslr-seed with a 64-bit value from source of entropy at boot. Add a fdt_kaslrseed function to accommodate this allowing an existing node to be overwritten if present. For now use the first rng device but it would be good to enhance this in the future to allow some sort of selection or policy in choosing the rng device used.
