      Revert "of: Feed entire flattened device tree into the random pool" · b920ecc8
      Grant Likely authored
      This reverts commit 109b6236.
      
      Tim Bird expressed concern that this will have a bad effect on boot
      time, and while simple tests have shown it to be okay with simple tree,
      a device tree blob can potentially be quite large and
      add_device_randomness() is not a fast function. Rather than do this for
      all platforms unconditionally, I'm reverting this patch and would like
      to see it revisited. Instead of feeding the entire tree into the random
      pool, it would probably be appropriate to hash the tree and feed the
      hash result into the pool. There really isn't a lot of randomness in a
      device tree anyway. In the majority of cases only a handful of
      properties are going to be different between machines with the same
      baseboard.

      of: fix unnecessary warning on missing /cpus node · 444c91e5
      Grant Likely authored
      Not all DT platforms have all the cpus collected under a /cpus node.
      That just happens to be a details of FDT, ePAPR and PowerPC platforms.
      Sparc does something different, but unfortunately the current code
      complains with a warning if /cpus isn't there. This became a problem
      with commit f86e4718, "driver/core cpu: initialize of_node in cpu's
      device structure", which caused the function to get called for all
      architectures.
      
      This commit is a temporary fix to fail silently if the cpus node isn't
      present. A proper fix will come later to allow arch code to provide a
      custom mechanism for decoding the CPU hwid if the 'reg' property isn't
      appropriate.
