It's not a hardware being sold this way, it's me doing the enablement
of some old HW and not noticing that default imx53.dtsi lists
frequencies up to 1.2 GHz. And it seems SHA-1 is the only one unit
affected by this overclocking. I have been running the board through
installation and tests without any obvious issues.

Ack. Didn't know that it doesn't notify maintainers. Please excuse me.
