50 Userspace IO interface to the Cryptography engine found on the
51 Nias Digital SMX boards. These will be available from Q4 2008
52 from http://www.niasdigital.com. The userspace part of this
53 driver will be released under the GPL at the same time as the
54 hardware and will be able to be downloaded from the same site.

56 If you compile this as a module, it will be called uio_smx.
