Currently when we boot a mx6dual U-boot reports that it is a mx6quad.

Report it as MX6D instead:

CPU:   Freescale i.MX6D rev1.2 at 792 MHz

Agree generally with the patch, but it seems to me better, instead of fixing the MX5 here, to move all CPU definitions outside the specific MX5/MX6 files into imx-common. They can be then defined once else in each sys_proto.h.

I have nothing against a new file, maybe cpu.h ?

Best regards,
Stefano Babic
