New Revision: 323721
URL: https://svnweb.freebsd.org/changeset/base/323721

Log:
  Add kern.features flag for MMCCAM
  
  kern.features.mmcam will be present and equal to 1 if the kernel has been
  compiled with option MMCCAM.
  This will help sdio-related userland tools to fail-fast if running on the kernel
  without MMCCAM enabled.
