The chip is advertised for having a HW i2c peripheral, but all the libs I saw simply bitbang it on GPIO pins, what's up with that mates?

Where did you see such claims? There's no externally available hardware i2c on this chip.

Here it is written in the spec:
Code: Select all8.4.1  Master SI / SPI Control (Optional)
The master serial interface (SI) can operate in two, three or four-wire bus configurations to  control the EEPROM or other I2C/SPI devices. Multiple I2C devices with different device addresses are supported by sharing the 2-wire bus.

Cool, any info about actually using the hardware i2c? I can't spot any info about it, registers'n'sh*t.
