| Subject: ARM: shmobile: Add shared R-Car Gen2 CMA reservation code |
| |
| Add R-Car Gen2 CMA memory reservation code that can be |
| shared between multiple SoCs and boards. At this point |
| r8a7790 and r8a7791 are supported. |
| |
| The top 256MiB of the legacy 32-bit physical memory space |
| is assigned to a separate CMA area that may be assigned |
| to various devices later on. |
