Improve support for custom device trees when kernel updates are received * Modified make-trees.sh so that it builds for all installed kernels. * A new script flash-latest.sh that copies the resulting .dtb files into the /etc/flash-kernel/dtbs/ override folder. The build-trees README is updated for this, and shows how to configure flash-kernel to use the custom .dtbs. Kernel upgrade should now go: [after a new kernel upgrade is installed] * Upgrade source: cd source && apt source linux-riscv * Build dtb's: cd build-trees &&; ./make_dtbs.sh * Install device tree via softlinks ./flash_latest.sh * Reboot

Notes:
|
|
- I2C pins 3,5,27 and 28 (PG13, PG12, PE17 and PE16) have 10K pullup resistors to 3v3
|
|
- The Status LED (PD18) is common with the LED_PWM pin on the DSI/LVDS output
