From: Christian Taedcke <[email protected]>
Without this commit the configuration node includes the compatible
line 'compatible = [00];' if EXTERNAL_KERNEL_DEVICETREE is not
defined, i.e. if PREFERRED_PROVIDER_virtual/dtb is not used.
This prevents u-boot from using this configuration and it prints the
message "Could not find configuration node".
An additional check also ensures that the written compatible line
never contains an empty compatible.
The functionality to add the compatible line was added in commit
f4c82fb6da89 ("kernel-fitImage: add machine compatible to config
section").
