Priyanka Jain 062ef1a662 powerpc/t104xrdb: Add T1040RDB board support
T1040RDB is Freescale Reference Design Board supporting
the T1040 QorIQ Power Architecture™ processor.

 T1040RDB board Overview
 -----------------------
 - Four e5500 cores, each with a private 256 KB L2 cache
 - 256 KB shared L3 CoreNet platform cache (CPC)
 - Interconnect CoreNet platform
 - 32-/64-bit DDR3L/DDR4 SDRAM memory controller with ECC and interleaving
   support
 - Data Path Acceleration Architecture (DPAA) incorporating acceleration
 for the following functions:
    -  Packet parsing, classification, and distribution
    -  Queue management for scheduling, packet sequencing, and congestion
       management
    -  Cryptography Acceleration
    - RegEx Pattern Matching Acceleration
    - IEEE Std 1588 support
    - Hardware buffer management for buffer allocation and deallocation
 - Ethernet interfaces
    - Integrated 8-port Gigabit Ethernet switch
    - Four 1 Gbps Ethernet controllers
 - SERDES Connections, 8 lanes supporting:
    - PCI
    - SGMII
    - QSGMII
    - SATA 2.0
 - DDR Controller 32-/64-bit DDR3L/DDR4 SDRAM memory controller with ECC and
   Interleaving
 -IFC/Local Bus
