| Subject: ARM: shmobile: Lager memory map update |
| |
| Update the Lager DTS to make use of the new unified legacy |
| memory map where the legacy window on Lager and Koelsch |
| have the same size. |
| |
| With this change in place the code gets aligned with the |
| documentation. |
| |
| After update the Lager board has the following map: |
| Bank0: 1GiB RAM (Legacy 32-bit: 0x40000000->0x7fffffff) |
| Bank1: 3GiB RAM (LPAE area: 0x140000000->0x1ffffffff) |
| |
| Before the update the old map looked like this: |
| Bank0: 2GiB RAM (Legacy 32-bit: 0x40000000->0xbfffffff) |
| Bank1: 2GiB RAM (LPAE area: 0x180000000->0x1ffffffff) |
| |
| Tested with and without LPAE on r8a7790 Lager. |
