    - EISA support for non PCI RMs (RM200 and RM400-xxx). The major part
      is the splitting of the EISA and onboard ISA of the RM200, which
      makes the EISA bus on the RM200 look like on other RMs.
    - 64bit kernel support
    - system type detection is now common for big and little endian
    - moved sniprom code to arch/mips/fw
    - added call_o32 function to arch/mips/fw/lib, which uses a private
      stack for calling prom functions
    - fix problem with ISA interrupts, which makes using PIT clockevent
      possible
