Watchdog device driver
A driver for stm32's Independent Watchdog (IWDG). It has been tested on
STM3210E-EVAL evaluation board, as well as on our proprietary board. Should
work with F4 (cortexm4) stm32 chips too, but not tested yet. This patch
contains the driver itself and amendments to ecos.db.
IWDG timeout (resolution) is based on LSI, an RC clock internal to stm32. This
time period can be configured by specifying both prescaler and reload value.
For convenience, the configtool displays the resulting timeout in microseconds,
calculated on nominal value of LSI clock.
