[yocto] Append to bblayers.conf and local.conf

[Olsson Rikard (RBSN/ESW1)]

Hello Yocto team,

We are receiving bblayer.conf and local.conf from external supplier which already have layers/configuration added. Now we want to add our own layers/configuration by appending to these files this to avoid manual merge work each time a delivery from external supplier is made.

Question:
How do I append layers/configuration to bblayer.conf and local.conf?

Best regards
Rikard Olsson
