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).
