  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).
