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