svn commit: r254424 - head/sys/dev/sdhci

[Ian Lepore]

Author: ian

New Revision: 254424
URL: http://svnweb.freebsd.org/changeset/base/254424

Log:
  Add named constants for 8-bit bus support.  The sdhci and mmc drivers
  don't have support for this yet, but some low-level hardware is ready
  for it when the higher layers catch up.
