Antoine Mazeas 6d06424949 rpi: Copy properties from firmware dtb to the loaded dtb ... The RPI firmware adjusts several property values in the dtb it passes to u-boot depending on the board/SoC revision. Inherit some of these when u-boot loads a dtb itself. Specificaly copy: * /model: The firmware provides a more specific string * /memreserve: The firmware defines a reserved range, better keep it * emmc2bus and pcie0 dma-ranges: The C0T revision of the bcm2711 Soc (as present on rpi 400 and some rpi 4B boards) has different values for these then the B0T revision. So these need to be adjusted to boot on these boards * blconfig: The firmware defines the memory area where the blconfig stored. Copy those over so it can be enabled. * /chosen/kaslr-seed: The firmware generates a kaslr seed, take advantage of that.
