-- gerrit commit 52f48b9e77457745f750a6d9278fa5801745136a Author: Uwe Bonnes <b...@elektron.ikp.physik.tu-darmstadt.de> Date: Fri Jan 9 10:53:30 2015 +0100 tcl: Add default hooks for STM32F4x Keep clocks running in low power modes. Stop watchdogs from interfering with the debug session. Set up PLL and increase clock at reset init.
