Update tooling for custom kernels (#6)
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

# A device tree for Raspberry PI HATs..
|
||||
|
||||
Designed to mimic the standard PI gpio assignments for use with PI HAT's
|
||||
* i2c**0** and spi**1** ports are located on the same Pins as the PI I2C-**1** and SPI-**0** on the PI gpio header
|
||||
* i2c3 is on the same pins as I2C-0 on the Pi (normally reserved as the Pi EEPROM Data pins)
