| 2 | * DaVinci CPU type detection | |
| 3 | * | |
| 4 | * Author: Kevin Hilman, Deep Root Systems, LLC | |
| 5 | * | |
| 6 | * Defines the cpu_is_*() macros for runtime detection of DaVinci | |
| 25985edc | 7 | * device type. In addition, if support for a given device is not |
| e653034e KH |
8 | * compiled in to the kernel, the macros return 0 so that |
| 9 | * resulting code can be optimized out. | |
