"""
Read in the cmsis/devinc/stm32f405xx.h header, extract relevant constants,
and create modstmconst.c.
This is not part of the automatic build process because stm32f405xx.h isn't
expected to change. After generating the file, some manual intervention is
needed to copy the new qstr definitions to qstrdefsport.h.
