54 * We do have 128MB of memory on the Vybrid Tower board. Leave the last
55 * 16MB alone to avoid conflicts with Cortex-M4 firmwares running from
56 * DDR3. Hence, limit the memory range for image processing to 112MB
57 * using bootm_size. All of the following must be within this range.
58 * We have the default load at 32MB into DDR (for the kernel), FDT at
59 * 64MB and the ramdisk 512KB above that (allowing for hopefully never
60 * seen large trees). This allows a reasonable split between ramdisk
61 * and kernel size, where the ram disk can be a bit larger.
