Instead of hardcoding the mx6 silicon revision, read it in run-time.
Also, besides the silicon version print the mx6 variant type: quad,dual/solo or solo-lite.
Tested on a mx6qsabrelite, where it shows:
CPU: Freescale i.MX6Q rev1.0 at 792 MHz

Hi Fabio,
Changes since v3:
- Provide a complete struct for anatop registers
Changes since v2:
- Read both chip variant and chip silicon version from anatop
- Create a struct for accessing the anatop registers
Changes since v1:
- Fix typo on Subject

I admit I have not yet tested, but does this statement generate a "unknown" on all MX5 boards ?
