Yes it's woking, on the 16 cores, I tested mi ephipany code using the
scrypt_1024_1_1_256_sp function and checking if the results was equal. The
speed is ~120h/s TMTO 100, I can make TMTO a little bit smaller but not to
much. BTW my driver should work on epiphany 64 with a little modification.
The code is submitted to my git repo

I just move the code to the master cgminer branch. I did that because maybe
we can propose to cKolivas add my epiphany driver to cgminer.

It was a little bug that I add when I change the name of the driver from
"CPU" to ยท"EPIPHANY" because the name can't be longer tan 8 characters,
epiphany support was working before it and now.

TMTO factor is 100  but hopefully it could be reduced up to ~20

My apologies I think that now everything must be more clear.
BTW I'm experimenting problems to connect to Parallella ZED and Parallella
embecosm boards.
