Hi Yannic,

second version of the series to add support for EEPROM SoM detection used by different PHYTEC SoMs. The EEPROM data consist of 32 bytes containing information like PCB revision, RAM size and other SoM specific configuration.
For SoMs of the i.MX8M family the data is written to two areas of the used i2c EEPROM.
We initally add the detection support for phyCORE-i.MX8MP. Due to layout constraints phyCORE-i.MX8MP SoMs with PCB revision 2 and older can only make use of a lower RAM frequency. This changes with the use of newer PCB revisions. We make use of the factory flashed EEPROM data to detect the PCB revision and select the fitting RAM settings.
Changes in v2:
- fix wrong RAM Timing values as pointed out by Yannic
- removed superfluous goto
- removed blank line at EOF
- fix string conversion to integer
- fix typo s/revsions/revisions
Could you please help review v2?
Thanks
