The loading address is too close to the kernel address, so newer kernels may overlap memory space, so loading the device tree may corrupt zImage. This patch moves the fdt_addr_r to 0x14000000 which is also consistent with guidance that the kernel be allocated 32MB. This places it in the same place as the ramdisk, so this patch moves the ramdisk address 512KB after the fdt.
