    ARM: initial multiplatform support · 387798b3
    Rob Herring authored
    This lets us build a multiplatform kernel for experimental purposes.
    However, it will not be useful for any real work, because it relies
    on a number of useful things to be disabled for now:
    
    * SMP support must be turned off because of conflicting symbols.
      Marc Zyngier has proposed a solution by adding a new SOC
      operations structure to hold indirect function pointers
      for these, but that work is currently stalled
    
    * We turn on SPARSE_IRQ unconditionally, which is not supported
      on most platforms. Each of them is currently in a different
      state, but most are being worked on.
    
    * A common clock framework is in place since v3.4 but not yet
      being used. Work on this is on its way.
    
    * DEBUG_LL for early debugging is currently disabled.
    
    * THUMB2_KERNEL does not work with allyesconfig because the
      kernel gets too big
    
    [Rob Herring]: Rebased to not be dependent on the mass mach header rename.
    As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank,
    picoxcell, mvebu, and socfpga are converted.
