The aesdec module has been hacked to use an OP-TEE TA to decrypt the stream into restricted DMA-bufs which are consumed by the kmssink.
Thanks so very much for putting this together btw. This is the exact thing we were just starting on, but you beat us to it by a few weeks it seems. It's awesome to have an implementation of 'real' (if useless) SVP, so we can actually exercise these codepaths in open generic code.
