Got GPIO kernel driver working in esp32s3 xtensa linux, and with that bitbanged SPI and I2C. Can scan i2c bus with i2cdetect. Got an example i2c accelerometer working in the kernel iio framework.

Got linux-6.7-rc8 + userspace running on esp32 with 4M FLASH and 4M PSRAM. It took some time to find a workaround for the unfortunate default FLASH mapping. Build script: github.com/jcmvbkbc/esp32…
