cmd: kaslrseed: add command to generate value from hwrng
Allow the kaslr-seed value in the chosen node to be set from a hardware
rng source.
Tested on a Rockchip PX30 (Odroid Go Advance), you must have loaded
the devicetree first and prepared it for editing. On my device the
workflow goes as follows:
setenv dtb_loadaddr "0x01f00000"
load mmc 0:1 ${dtb_loadaddr} rk3326-odroid-go2.dtb
fdt addr ${dtb_loadaddr}
fdt resize
kaslrseed
and the output can be seen here:
fdt print /chosen
chosen {
kaslr-seed = <0x6f61df74 0x6f7b996c>;
stdout-path = "serial2:115200n8";
};
