  • Add QUICC Engine (QE) configuration, header files, and
    QE management and library code that are used by QE devices
    drivers.

    Includes Leo's modifications up to, and including, the
    platform_device to of_device adaptation:

    "The series of patches add generic QE infrastructure called
    qe_lib, and MPC8360EMDS board support. Qe_lib is used by
    QE device drivers such as ucc_geth driver.

    This version updates QE interrupt controller to use new irq
    mapping mechanism, addresses all the comments received with
    last submission and includes some style fixes.

    v2: Change to use device tree for BCSR and MURAM;
    Remove I/O port interrupt handling code as it is not generic
    enough.

    v3: Address comments from Kumar; Update definition of several
    device tree nodes; Copyright style change."

    In addition, the following changes have been made:

    o removed typedefs
    o uint -> u32 conversions
    o removed following defines:
    QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
    BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
    because they hid sizeof/in_be32/out_be32 operations from the reader.
    o fixed qe_snums_init() serial num assignment to use a const array
    o made CONFIG_UCC_FAST select UCC_SLOW
    o reduced NR_QE_IC_INTS from 128 to 64
    o remove _IO_BASE, etc. defines (not used)
    o removed irrelevant comments, added others to resemble removed BD_ defines
    o realigned struct definitions in headers
    o various other style fixes including things like pinMask -> pin_mask
    o fixed a ton of whitespace issues
    o marked ioregs as __be32/__be16
    o removed platform_device code and redundant get_qe_base()
    o removed redundant comments
    o added cpu_relax() to qe_reset
    o uncasted all get_property() assignments
    o eliminated unneeded casts
    o eliminated immrbar_phys_to_virt (not used)
