  RegEx Pattern Matching Acceleration (PME 2.1) at up to 10 Gbps
  Decompression/Compression Acceleration (DCE 1.0) at up to 20 Gbps
  DPAA chip-to-chip interconnect via RapidIO Message Manager (RMAN 1.0)
32 SerDes lanes at up to 10.3125 GHz
Ethernet interfaces
  Up to four 10 Gbps Ethernet MACs
  Up to sixteen 1 Gbps Ethernet MACs
  Maximum configuration of 4 x 10 GE + 8 x 1 GE
High-speed peripheral interfaces
  Four PCI Express 2.0/3.0 controllers
  Two Serial RapidIO 2.0 controllers/ports running at up to 5 GHz with
    Type 11 messaging and Type 9 data streaming support
  Interlaken look-aside interface for serial TCAM connection
Additional peripheral interfaces
  Two serial ATA (SATA 2.0) controllers
  Two high-speed USB 2.0 controllers with integrated PHY
  Enhanced secure digital host controller (SD/MMC/eMMC)
  Enhanced serial peripheral interface (eSPI)
  Four I2C controllers
  Four 2-pin or two 4-pin UARTs
  Integrated Flash controller supporting NAND and NOR flash
Two eight-channel DMA engines
Support for hardware virtualization and partitioning enforcement
QorIQ Platform's Trust Architecture 1.1
