* 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.
