| 13 | * This file supports the three variants of Armada XP SoCs that are |
| 14 | * available: mv78230, mv78260 and mv78460. From a pin muxing |
| 15 | * perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460 |
| 16 | * both have 67 MPP pins (more GPIOs and address lines for the memory |
| 17 | * bus mainly). The only difference between the mv78260 and the |
| 18 | * mv78460 in terms of pin muxing is the addition of two functions on |
| 19 | * pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two |
| 20 | * cores, mv78460 has four cores). |
