Subject: [PATCH v2 0/6] PHYTEC SoM detection for phyCORE-i.MX8MP
Date: Thu, 17 Aug 2023 10:57:05 +0200 [thread overview]
Message-ID: <20230817085711.45339-1-t.remmet@phytec.de> (raw)
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
