    ppc/powerpc: workarounds for old Open Firmware versions · a23414be
    Paul Mackerras authored
    This adds code to work around some problems with old versions of
    Open Firmware, such as on the early powermacs (7500 etc.) and the
    "Longtrail" CHRP machine.  On these machines we have to claim
    the physical and virtual address ranges explicitly when claiming
    memory and then set up a V->P mapping.
    The Longtrail has more problems: setprop doesn't work, and we have
    to set an "allow-reclaim" variable to 0 in order to get claim on
    physical memory ranges to fail if the memory is already claimed.
