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
