This is a good point ! If it is true that L2 PREFETCH is turned on in mainline kernel, but it was *explicitely* turned off by Jason in FSL Kernel with the patch with subject ENGR00278489 (ARM PL310 errata: 7522719). It seems to me that Fabio has already applied Jason's patch - maybe should we check as in FSL kernel which i.MX6 is running (DL and Solo are not affected). Jason, can you a little explain this topic ? Was the patch sent to Shaw, too (set in CC) ?
