* Patch by Denis Peter, 8 Dec 2003

  - add support for the PATI board (MPC555)
  - add SPI support for the MPC5xx

* Patch by Anders Larsen, 08 Dec 2003:
  add configuration options CONFIG_SERIAL_TAG and CONFIG_REVISION_TAG
  to pass ATAG_SERIAL and ATAG_REVISION, resp., to the ARM target;
  cleanup some redundand #defines
