The commited VM_MAX_KERNEL_ADDRESS fix includes a page more memory than what's in the snap, it would be nice to confirm that the committed version works as well. The eeprom is hooked up via i2c and will need imxiic in novena_devs[] and likely some additional imxiic changes from Patrick. Getting at the atheros wlan/mini pcie slot would need something along the lines of Patrick's imxpcibr work. Audio looks to need a new driver for the ES8328 hooked up to imx via gpio/i2c?

Compiling u-boot is painful, I tried to do it natively on bbb but gave up as it seems to expect linux headers. Just modifiying uEnv.txt is much easier.
