[maemo-developers] N900 AES and SHA1/MD5 hw acceleration drivers

[From: Tobias Karnat]

Hi,

Good news!!

The omap-aes driver has been fixed, it does now work without crashing.

The diff can be found here:
http://pastebin.com/PMt2j1Hs

omap-hw modules (incl. src.) compiled against PR1.3 can be found here:

But you will still need to update Nolo, load the required modules
(dm-mod, dm-crypt, hash-algorithm) and use cryptsetup to work with it.

The src of the modules including Nolo can still be found here:
http://www.mediafire.com/?cc1vbsnwnho31vb

But you will need to compile the src again. Since the modules were
compiled against PR1.2.
