I am using CodeWarrior™ Development Studio for MPC55xx/MPC56xx Version 2.10 with the PowerPC MPC5644A (core e200z4). I don't know if a documentation with explanations on LCF file exists.
please look at the documents in the attachment. These documents are part of CodeWarrior installation. Both documents are similar (almost the same), but it is possible there are some details, which could be helpful for you.
