[U-Boot] [PATCH AT91] Add watchdog reset to the at91samx SOC family

Dear Michael Trimarchi,

NAK.

Watchdog already exists at drivers/watchdog/at91sam9_wdt.c :)

Maybe its a bit of an obscure location... But it is already invented ;)

Besides... why would we need to disable IRQs here, writel() is using one instruction
to write to the address?
