Thanks for the tip.

I've added a .S file for the additional assembly code to be link with
sha512.c, but apparently import_gcry.py doesn't know how to preprocess
this file:
WARNING: unknown file sha512-sse2-x86.S
gcry_sha512
I've read import_gcry.py but the preprocessing is pretty complicated.
What is the correct way to make my assembly code be recognized and
preprocessed as a grub module by the script?
Cheers,
Tom Li
