Public bug reported:

Please enable CONFIG_SCOM_DEBUGFS for ppc64el kernels, this creates some
new files in debugfs that allow userspace (root only) to access the
P7/P8 chip internal XSCOM bus, which is needed for  various
debug/diag/mfg tools. There should be no runtime impact on performance
or stability by just enabling that option.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete
