Hi Ard,
Thanks for all the inputs.

Alternatively, a SHA-256 implementation that uses movz/movk sequences

I-cache.
Actually, looking at the C code and the objdump of the kernel's
sha256_generic driver, it is likely that it is already doing this, and
none of the points I made actually make a lot of sense ...
Pratyush: I assume you are already enabling the I-cache in the purgatory?
It's not enabled yet. But, I had tried first with enabling only I-cache, but
that did not make much difference in execution time.
