Unfortunately, I can't make any sense of this series. First of all, the
IS25LX256 [1] doesn't support 8S-8S-8S, only 8D-8D-8D and 1S-8S-8S, see
ch. 4. Confused, I've looked at your octal str enable function and it 
writes
0xc7 to the volatile configuration register 0x00. According to the 
datasheet,
that is the enable for the octal DTR mode.

Please explain your problem and your motivation in the cover 
letter/commit
message and how you fix it.
