[U-Boot] [PATCH 2/2] at91sam9263ek: active watchdog support via at91sam9263ek_wdt_config

[Giulio Benetti]

In this way the linux driver won't work(the one by Renaud CERRATO).
Because it expects MR register not to be set, or to be set enabled.

After I don't agree refreshing watchdog inside atmel_usart.c
If u-boot hangs there instead of execute bootcmd, then the machine lies
there forever.
In my opinion we should put WATCHDOG_RESET() inside main_loop and nand write
and read.
What do you think?

Kind regards
