svn commit: r342255 - in head: . sys/mips/conf sys/mips/mips sys/mips/sibyte

[Warner Losh]

Author: imp
Date: Wed Dec 19 22:54:03 2018
New Revision: 342255
URL: https://svnweb.freebsd.org/changeset/base/342255

Log:
  Remove support for the now very old SiByte MIPS platform. It's not
  relevant and is unused. It's also getting in the way of progress in
  some admittedly minor ways. Better to retire it to reduce the burden
  on the project.
