| Contiguous Memory Allocator requires only paging and MMU enabled not |
| particular CPU architectures, so there is no need for strict dependency |
| on CPU type. This enables to use CMA on some older ARM v5 systems which |
| also might need large contiguous blocks for the multimedia processing hw |
| modules. |
