From: sandiecao <sandie.cao@deepcomputing.io>

The FML13V05 board from DeepComputing incorporates a SpacemiT K3 RISC-V
SoC.It is a mainboard designed for the Framework Laptop 13 Chassis,
which has (Framework) SKU FRANHQ0001.

The FML13V05 board features:
- SpacemiT K3 RISC-V SoC
- LPDDR5 16GB or 32GB
- eMMC 32GB ~128GB (Optional)
- UFS 3.1 256G (Optional)
- QSPI Flash
- MicroSD Slot
- PCIe-based Wi-Fi
- 4 USB-C Ports
- Port 1: PD 3.0 (65W Max), USB 3.2 Gen 1
- Port 2: PD 3.0 (65W Max), USB 3.2 Gen 1, DP 1.4 (4K@60Hz)
- Port 3 & 4: USB 3.2 Gen 1

This minimal device tree enables booting into a serial console with UART
output.
