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). 21 */ 22 23 #include <linux/err.h> 24 #include <linux/init.h> 25 #include <linux/io.h> 26 #include <linux/module.h> 27 #include <linux/platform_device.h> 28 #include
