Yann Gautier	21cfa4531a	fix(stm32mp1): do not reopen debug features ... On closed chips, it is not allowed to open debug. The BSEC debug register can not be rewritten. On open chips, the debug is already open, no need to rewrite this register. This part of code is just removed. An INFO message is displayed if debug is disabled. The freeze of the watchdog during debug is also removed. In case of debug, this must be managed by the software that enables the debugger.

Yann Gautier	dec286dd7d	stm32mp1: print information about SoC ... This information is located in DBGMCU registers. Change-Id: I480aa046fed9992e3d9665b1f0520bc4b6cfdf30 Signed-off-by: Yann Gautier <yann.gautier@st.com>	2019-09-02 17:49:30 +02:00
Yann Gautier	73680c230f	stm32mp1: add watchdog support ... Introduce driver for STM32 IWDG peripheral (Independent Watchdog). It is configured according to device tree content and should be enabled from there. The watchdog is not started by default. It can be started after an HW reset if the dedicated OTP is fused. The watchdog also needs to be frozen if a debugger is attached. This is done by configuring the correct bits in DBGMCU. This configuration is allowed by checking BSEC properties. An increase of BL2 size is also required when adding this new code.
