      ====================
      Freescale DPAA FMan
      
      The Freescale Data Path Acceleration Architecture (DPAA) is a set
      of hardware components on specific QorIQ multicore processors.
      This architecture provides the infrastructure to support
      simplified sharing of networking interfaces and accelerators
      by multiple CPU cores and the accelerators.
      
      One of the DPAA accelerators is the Frame Manager (FMan)
      which contains a series of hardware blocks: ports, Ethernet MACs,
      a multi user RAM (MURAM) and Storage Profile (SP).
      
      This patch set introduce the FMan drivers.
      Each driver configures and initializes the corresponding
      FMan hardware module (described above).
      The MAC driver offers support for three different
      types of MACs (eTSEC, TGEC, MEMAC).

      fsl/fman: Add FMan Port Support · 18a6c85f
      Igal Liberman authored
      Add the Data Path Acceleration Architecture Frame Manger Port Driver.
      The FMan driver uses a module called "Port" to represent the physical
      TX and RX ports.
      Each FMan version has different number of physical ports.
      This patch adds The FMan Port configuration, initialization and
      runtime control routines for both TX and RX.

      Add the Data Path Acceleration Architecture Frame Manger Driver.
      The FMan embeds a series of hardware blocks that implement a group
      of Ethernet interfaces. This patch adds The FMan configuration,
      initialization and runtime control routines.
      
      The FMan driver supports several hardware versions
      differentiated by things like:
      	- Different type of MACs
      	- Number of MAC and ports
      	- Available resources
      	- Different hardware errata

      fsl/fman: Add FMan MURAM support · 5adae51a
      Igal Liberman authored
      Add Frame Manager Multi-User RAM support.
      This internal FMan memory block is used by the
      FMan hardware modules, the management being made
      through the generic allocator.
      
      The FMan Internal memory, for example, is used for
      allocating transmit and receive FIFOs.
