New Revision: 322015
URL: https://svnweb.freebsd.org/changeset/base/322015

Log:
  Add an ahci driver for imx6.
  
  This was submitted by Rogiel Sulzbach (thank you!) but has a few last-minute
  changes by me, mostly where the code interfaces to my still-utterly-deficient
  imx6_ccm clocks implementation.  So blame me for any mistakes.
