[KICKOFF] add minimal code to build for Raspberry Pi boards
Add recipes and bbappend files for Raspberry Pi following CleaOS new structure for Scarthgap.
BSP info:
- kernel > linux-raspberrypi 6.6 (relies on kernel recipe in meta-raspberrypi)
- bootloader > upstream U-boot 2025.01-rc2 (new recipe)
This layer also enables the serial port on GPIO 14/15.
The kernel bbappend
file only includes linux-seco.inc
from meta-seco-bsp
.
The U-boot recipe builds the latest (at the time of writing) version of U-boot.
This version includes patches
that add some basic support for the Raspberry Pi 5. It does NOT yet support the uart0
serial
port on GPIO 14/15 (driver missing).
