| * DaVinci CPU type detection |

| * Author: Kevin Hilman, Deep Root Systems, LLC |
| * |
| * Defines the cpu_is_*() macros for runtime detection of DaVinci |
| * device type. In addition, if support for a given device is not |
| * compiled in to the kernel, the macros return 0 so that |
| * resulting code can be optimized out. |
