WDT is the Watchdog timer. WDC registers are located at the memory range at [0x1e785000, 0x1e785fff]. There are currently up to 8 watchdog timers in the range, of which 2 are being used by AST2500. Refer to them with macros named AST_REG_WDT<n>, where <n> is the byte offset into the watchdog timer's memory range. Each macro also takes the index of the watchdog timer to access. A new watchdog timer starts at each 0x40 byte offset.
