2023-01-31board: gateworks: venice: poll I2C lines to wait for GSC firmwareTim Harvey
In some situations the GSC firmware where the EEPROM containing the model and DRAM configuration may not be ready by the time the SoC is ready to talk to it over I2C. Instead of a hard delay, poll the I2C lines to wait until they are released to avoid the I2C drivers 'Arbitation lost' error message.
