Hi Andy.
Another imx6 user reported that disabling the cache "write-allocate" did
improve performances tremendously, I just tried on omap4, and latencies
seem to improve. So, this looks like the solution.
The patch you will find here:
http://sisyphus.hd.free.fr/~gilles/mx6.patch
Disables "write-allocate" for imx6 using the L2 cache controller
auxiliary register bits 23 and 24.
Regards.
