-- gerrit commit 430cc0685d5112abb36b358edf96c97b12cb5694 Author: Spencer Oliver <[email protected]> Date: Mon Apr 30 14:29:18 2012 +0100 flash: use correct stm32f0 flash size register The stm32f0 parts use a different address then the rest of the family. Add a function that returns the correct FLASH_SIZE reg depending on variant.
