At the moment it seems to me that the revision number corresponds 1:1 to
the value of the register in the i.MX53, and we do not need some mapping
as for i.MX51. What about to drop the switch and adding a simpler:
if (reg < 0x20)
system_rev |= CHIP_REV_1_0;
else
system_rev |= reg;
Best regards,
Stefano
