Add support for the CMCC RAX3000Q/QY platform based on Qualcomm IPQ5000.
Both hardware variants are identical and share the same device tree.
Hardware Specifications:
- SoC: Qualcomm IPQ5000
- RAM: 256 MiB, integrated in SoC
- Flash: GigaDevice GD5F1GQ5REYIG (Dosilicon variant is not supported)
- 2.4 GHz Wi-Fi: SoC integrated, with 2 FEMs
- 5 GHz Wi-Fi: QCN6102, with 2 FEMs
- Switch: QCA8337, 1 WAN + 3 LAN
- LEDs: 3 RGB LEDs
- Keys: reset and mesh pairing
- UART: 3-pin, 115200n8
The vendor flash layout is documented and the ART partition contains
calibration data, which must be preserved carefully.
Due to the limited 256 MiB RAM, ath11k is disabled in the DTS to avoid
OOM issues on this device.
The MAC address location in flash could not be identified reliably.
As a temporary workaround, the MAC addresses (WAN LAN 2.4G 5G WiFi) are derived from the ART
partition start, with vendor/default values being invalid and falling
back to random generation if left unchanged (FF).
