SEC h/w versions 2.1 and above support sha224 via explicit instruction. Performing sha224 ahashes on earlier versions is still possible because they support sha256 (sha224 is sha256 with different initial constants and a different truncation length). We do this by overriding hardware context self-initialization, and perform it manually in s/w instead. Thanks to Lee for his fixes for correct execution on actual sec2.0 h/w.
