I had another look at Freescale-chc12.cmake.

I guess you have different projects using this controller ?

In the file you have the cache variables HC12_LINK_PRM_FILE, 
HC12_MEMORY_MODEL_LETTER and HC12_CORE. I guess they don't depend on 
preferences of the users but on how the actual hardware for this project 
looks like. Does this mean in order to build these projects correctly the 
user/developer has to adjust these variables manually to the correct values 
for the target hardware ?

If that's the case then IMO this is not ideal, this is what I wanted to go to 
the Freescale-chc12-hc12.cmake file. But this won't work (without repeating 
really a lot of code there) if the "processor" file is executed after 
the "compiler" file, because then the rules-variables will already have been 
set. 
How about including the "processor" file before the "compiler" file ?
Then you could have Freescale-chc12-product1.cmake which would set HC12_CORE 
etc. as required for this project.

What do you think ?
