Why you give up mx23/mx28 register define role, which generate from SOC xml. 
There is a set header files for each mx23/mx28 module, which generate from xml.  
I know original header files affect run time one Image. 
But I think we can copy common part of such register definition because
That keep consistent with mx23/mx28 data sheet. Data sheet and header file generate
from one source xml.

HW_<Module name>_<Register name>.
BM_<Module name>_<Register name>_Bit name.
