      xtensa: add device trees support · da844a81
      Max Filippov 提交于
      Device trees allow specification of hardware topology and device
      parameters at runtime instead of hard-coding them in platform setup
      code. This allows running single binary kernel on a range of compatible
      boards.
      
      New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat
      device tree is passed in it.
      
      Note that current interrupt mapping scheme uses single cell for
      interrupt identification. That means that IRQ numbers used in DTS must
      be CPU internal IRQ numbers, not external. It is possible to extend
      interrupt identification to two cells, and use second cell to tell
      external IRQ numbers form internal. That would allow to use single DTS
      on multiple boards with different mapping of external IRQ numbers.
