? components.bluetooth: hci_uart is seen on the 2016 and 2017 models; no observed MacBook8,1 boot logs Bluetooth, so the same UART attachment is assumed.

Research notes (unverified)

Fanless 12-inch Retina MacBook with a single USB-C port (charging, USB and DisplayPort through an adapter).
Keyboard, trackpad and backlight connect over SPI (in-kernel applespi driver). Bluetooth is on UART (hci_uart). The FaceTime HD camera is a PCIe device needing the out-of-tree facetimehd driver.
BCM4350 Wi-Fi uses brcmfmac.
