New Revision: 185099
URL: http://svn.freebsd.org/changeset/base/185099

Log:
  Initial storage functionality for U-Boot support library.
  
  - Only non-sliced bsdlabel style partitioning is currently supported (but provisions
    are made towards GPT support, which should follow soon)
  - Enable storage support in loader on ARM
