/* The SAMA5D4 series devices are similar to the SAMA5D3 family except that:
 *
 * - Some parts support a 32-bit DDR data path (SAMA5D42 and SAMA5D44)
 * - Some parts support a Video Decoder (SAMA5D43 and SAMA5D44)
 * - Includes an L2 data cache, NEON FPU, and TrustZone
 * - New XDMAC DMA controller
 * - There are few differences in the support peripherals.  As examples:
 *   Gigbit Ethernet is not supported, for example; 10/100Base-T Ethernet
 *   is different.  Additional instances of peripherals:  USART4, TWI3,
 *   and SPI2.
