York Sun d2404141f9 powerpc/mpc85xx: Add B4860 and variant SoCs
Add support for Freescale B4860 and variant SoCs. Features of B4860 are
(incomplete list):

Six fully-programmable StarCore SC3900 FVP subsystems, divided into three
    clusters-each core runs up to 1.2 GHz, with an architecture highly
    optimized for wireless base station applications
Four dual-thread e6500 Power Architecture processors organized in one
    cluster-each core runs up to 1.8 GHz
Two DDR3/3L controllers for high-speed, industry-standard memory interface
    each runs at up to 1866.67 MHz
MAPLE-B3 hardware acceleration-for forward error correction schemes
    including Turbo or Viterbi decoding, Turbo encoding and rate matching,
    MIMO MMSE equalization scheme, matrix operations, CRC insertion and
    check, DFT/iDFT and FFT/iFFT calculations, PUSCH/PDSCH acceleration,
    and UMTS chip rate acceleration
CoreNet fabric that fully supports coherency using MESI protocol between
    the e6500 cores, SC3900 FVP cores, memories and external interfaces.
    CoreNet fabric interconnect runs at 667 MHz and supports coherent and
    non-coherent out of order transactions with prioritization and
    bandwidth allocation amongst CoreNet endpoints.
Data Path Acceleration Architecture, which includes the following:
  Frame Manager (FMan), which supports in-line packet parsing and general
    classification to enable policing and QoS-based packet distribution
  Queue Manager (QMan) and Buffer Manager (BMan), which allow offloading
    of queue management, task management, load distribution, flow ordering,
    buffer management, and allocation tasks from the cores
  Security engine (SEC 5.3)-crypto-acceleration for protocols such as
    IPsec, SSL, and 802.16
  RapidIO manager (RMAN) - Support SRIO types 8, 9, 10, and 11 (inbound and
    outbound). Supports types 5, 6 (outbound only)
Large internal cache memory with snooping and stashing capabilities for
    bandwidth saving and high utilization of processor elements. The
    9856-Kbyte internal memory space includes the following:
  32 Kbyte L1 ICache per e6500/SC3900 core
  32 Kbyte L1 DCache per e6500/SC3900 core
  2048 Kbyte unified L2 cache for each SC3900 FVP cluster
  2048 Kbyte unified L2 cache for the e6500 cluster
  Two 512 Kbyte shared L3 CoreNet platform caches (CPC)
Sixteen 10-GHz SerDes lanes serving:
  Two Serial RapidIO interfaces. Each supports up to 4 lanes and a total
    of up to 8 lanes
  Up to 8-lanes Common Public Radio Interface (CPRI) controller for glue-
    less antenna connection
  Two 10-Gbit Ethernet controllers (10GEC)
  Six 1G/2.5-Gbit Ethernet controllers for network communications
  PCI Express controller
  Debug (Aurora)
Two OCeaN DMAs
Various system peripherals
182 32-bit timers
