| 11 | * Note: this Device Tree assumes that the bootloader has remapped the | |
| 12 | * internal registers to 0xf1000000 (instead of the old 0xd0000000). | |
| 13 | * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot | |
| 14 | * bootloaders provided by Marvell. It is used in recent versions of | |
| 15 | * DSM software provided by Synology. Nonetheless, some earlier boards | |
| 16 | * were delivered with an older version of u-boot that left internal | |
| 17 | * registers mapped at 0xd0000000. If you have such a device you will | |
| 18 | * not be able to directly boot a kernel based on this Device Tree. In | |
| 19 | * that case, the preferred solution is to update your bootloader (e.g. | |
| 20 | * by upgrading to latest version of DSM, or building a new one and | |
| 21 | * installing it from u-boot prompt) or adjust the Devive Tree | |
| 22 | * (s/0xf1000000/0xd0000000/ in 'ranges' below). | |

| 70 | * Synology u-boot uses its compiled-in environment | |
| 71 | * and it seems Synology did not care to change u-boot | |
| 72 | * default configuration in order to allow saving a | |
| 73 | * modified environment at a sensible location. So, | |
| 74 | * if you do a 'saveenv' under u-boot, your modified | |
| 75 | * environment will be saved at 1MB after the start | |
| 76 | * of the flash, i.e. in the middle of the uImage. | |
| 77 | * For that reason, it is strongly advised not to | |
| 78 | * change the default environment, unless you know | |
| 79 | * what you are doing. | |
