Tested-by Thomas Petazzoni <[email protected]>

I've tested on an Armada 375 A0 platform. Before this series, due to the SSCG, I had a lot of drift in the system time. With this series, the platform now uses the 25 Mhz timer not affected by the SSCG, and I'm no longer experiencing any drift.

Thanks!

Thomas
