We would like to use ordt to generate C header files from our SystemRDL files for people who are writing C and C++ drivers for our hardware.

We would like to have defines for each address offset (and struct style too), field msb and lsb and width at least. I can provide test-cases (input and expected output), if somebody is willing to work on this.
