Hi Sebastian,

Is this patch different from that one:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg92176.html

Lokesh just pointed me this patch because it was missing for the 
SHAM/AES series from Mark Greer.

Bottom-line, I've just applied the original one along with a second one 
that was adding EDMA in SPI.

Regards,
Benoit
