HAT Connector GPIO mapping to SoC GPIO
I'm developing a custom board for the Hat. I was wondering which specific SoC pins (BGA pads) map to which pins on the GPIO hat connector. Some are obvious, but with Intel GPIO pins some are reprogrammable. I would like to bring out a second I2S if possible to the Hat. I realize I will be on my own with customizing drivers etc and the pins are driven through the CPLD.
