Currently working: - UFS and microSD - USB host (OTG) - WiFi - Bluetooth - Remoteprocs (ADSP, CDSP and modem) WiFi, Bluetooth and the remoteprocs need device-specific firmware, which is not part of this series. WiFi additionally needs qrtr, tqftpserv and rmtfs running in userspace, and the Bluetooth controller needs its BD address set from userspace. Display panel, touchscreen, and the GPU display pipeline will be added later, so the display is currently only available through simple-framebuffer.
