60  * DDR3. Hence, limit the memory range for image processing to 112MB
61  * using bootm_size. All of the following must be within this range.
62  * We have the default load at 32MB into DDR (for the kernel), FDT at
63  * 64MB and the ramdisk 512KB above that (allowing for hopefully never
64  * seen large trees). This allows a reasonable split between ramdisk
65  * and kernel size, where the ram disk can be a bit larger.
