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

[From: Tobias Karnat]

Hi,

Some might already know that Nokia has recently released a driver for
AES and SHA1+MD5 hardware acceleration on the linux-crypto mailing list,
however these drivers where based against 2.6.35 and needed the kernel
to be rebuild in order to use them, because the platform device driver
was to be build in the kernel. 

I have modified the driver in order to compile with the stock Nokia
kernel on the N900 and without requiring the kernel to be changed, they
do load...

However the omap-aes driver has problems if used in 256-Bit Cbc-Essiv
mode and if used in 128-Bit mode it causes the N900 to not wake up from
powersaving. The omap-sha1-md5 driver seems to be so far fine, but the
digest size in /proc/crypto looks somehow suspicious.

It would be very helpful, if someone could bug test the drivers as well,
since I don't have much experience with kernel modules. You will need to
update NOLO, since the M-Shield the N900 has, needs to be configured
differently, please make sure your N900 has hardware revision 2101 at
least.

I attached the NOLO update and the hw crypto modules, the source and the
patches are also included. Cryptsetup can be found in extra-devel, the
required dm-crypt and hash modules are also attached.
