File format

The file consists out of a 0x200 big header (though the actual header is only 0x30 bytes, the rest is zerofilled), plus data whose size is indicated in the header.

Reading

If 0x1FF81006 is 3 or 4 or 7 or 8 or 9 then the callibration data is read from the EEPROM using the i2c:EEP service command 0x001000C0, using offset 0x000 for HWCAL0, and offset 0x800 for HWCAL1. Otherwise attempt is made to read CTRNAND:/ro/sys/HWCAL(0|1).dat instead.
