[PATCH 0/6] Add support for IPQ5018 Bluetooth

[George Moussalem via B4 Relay]

Hello,

This patch series introduces Bluetooth support for IPQ5018.

Bluetooth firmware on the IPQ5018 platform runs on the M0 co-processor.
The firmware is loaded by the host into a dedicated reserved memory
carveout and authenticated by TrustZone. A Secure Channel Manager (SCM)
call safely brings the peripheral core out of reset.

A shared memory ring buffer topology handles runtime data frame
transport between the host APSS and the M0 core. An outgoing APCS IPC
bit and an incoming GIC interrupt handle host/guest signaling.

This series has been tested and verified on various IPQ5018 router
boards utilizing firmware extracted from GPL distributions, using both
mdt and mbn file formats.
