SAMV7: Watchdog: fix Forbidden Window Value
...
According the Datasheet the WDD Value is the lower bound of a so called Forbidden Window and to disable this we have to set the WDD
Value greater than or equal to the WDV Value. This seems to be a bug in the datasheet. It looks like we have to set it to a greater value than the WDV to realy disable this Thing. When triggering the Watchdog faster than the (very slow) clock source of the Watchdog fires, this Forbidden Window Feature resets the System if WDD equals to WDV.
This Changeset disables the Forbidden Window by setting the WDD Value to the Maximum (0xfff) Value possible.

STM32F7: add warning for RXDMA + IFLOWCONTROL combination
...
Combination of RXDMA + IFLOWCONTROL does not work as one might expect.
Since RXDMA uses circular DMA-buffer, DMA will always keep reading new
data from USART peripheral even if DMA buffer underruns. Thus this
combination only does following: RTS is asserted on USART setup and
deasserted on shutdown and does not perform actual RTS flow-control.
Data loss can be demonstrated by doing long up_mdelay inside irq
critical section and feeding data to RXDMA+IFLOWCONTROL UART.
