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) Signed-off-by: Li Yang <leoli@freescale.com> Signed-off-by: Shlomi Gridish <gridish@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
