This patch contains the salsa20-i586 implementation. The original
assembly code came from
<http://cr.yp.to/snuffle/salsa20/x86-pm/salsa20.s>. I have reformatted
it (added indents) so that it matches the other algorithms in
arch/x86/crypto.
This patch also contains a speed test for salsa20-i586. Usage is
"modprobe tcrypt mode=206"
Signed-off-by: Tan Swee Heng <thesweeheng@xxxxxxxxx>
====
Note: this is a resubmission; previously the indentation in the
assembly code was missing.
