yes, if you are not in a hurry to commit your patches, I guess together we can 
find a suitable solution.

as already mentioned, my goal is to automate as much as possible the MCU 
definition.

for example, in addition to the bitfield definitions that will be generated 
from the svd files, I identified and implemented bitfields that are 
automatically updated when other bitfields change, like READY bits 
automatically following ENABLE bits.

this is implemented with some bitfield properties, like:

        cm_object_property_set_str(state->f1.cr.pllrdy, "pllon", "follows");

or

        cm_object_property_set_str(state->f1.cir.lsirdyf, "lsirdyc",
                    "cleared-by");

such definitions greatly simplify the post-write callbacks.
