8 | * The various ARMv7 SoCs from TI all share a number of IP blocks when | |
9 | * implementing a given feature. Rather than define these in every | |
10 | * board or even SoC common file, we define a common file to be re-used | |
11 | * in all cases. While technically true that some of these details are | |
12 | * configurable at the board design, they are common throughout SoC | |
13 | * reference platforms as well as custom designs and become de facto | |
14 | * standards. | |
