New Revision: 264762
URL: http://svnweb.freebsd.org/changeset/base/264762

Log:
  MFC: r264257, r264327, r264514
  
  Distinguish between the different variants and configurations of Sunix
  {MIO,SER}5xxxx chips instead of treating all of them as PUC_PORT_2S.
  Among others, this fixes the hang seen when trying to probe the none-
  existent second UART on an actually 1-port chip.
