I did some work on an embedded product a while ago that had a hardware
encryption accelerator built into the SoC.  It required a kernel
driver and a patch to the OpenSSL library I think.  After enabling it,
our CPU load dropped by 50%.

So the moral of the story is to check what SoC or CPU supports h/w
acceleration, and if the kernel already has support for this feature.
Vendors are starting to catch on to the fact that if they get their
drivers into the mainline kernel, they will sell more hardware.
