+/*
+ * Watchdog driver for SiByte SB1 SoCs
+ *
+ * Copyright (C) 2007 OnStor, Inc. * Andrew Sharp <andy.sharp@onstor.com>
+ *
+ * This driver is intended to make the second of two hardware watchdogs
+ * on the Sibyte 12XX and 11XX SoCs available to the user.  There are two
+ * such devices available on the SoC, but it seems that there isn't an
+ * enumeration class for watchdogs in Linux like there is for RTCs.
+ * The second is used rather than the first because it uses IRQ 1,
+ * thereby avoiding all that IRQ 0 problematic nonsense.
+ *
+ * I have not tried this driver on a 1480 processor; it might work
+ * just well enough to really screw things up.
+ *
+ * It is a simple timer, and there is an interrupt that is raised the
+ * first time the timer expires.  The second time it expires, the chip
+ * is reset and there is no way to redirect that NMI.  Which could
+ * be problematic in some cases where this chip is sitting on the HT
+ * bus and has just taken responsibility for providing a cache block.
+ * Since the reset can't be redirected to the external reset pin, it is
+ * possible that other HT connected processors might hang and not reset.
+ * For Linux, a soft reset would probably be even worse than a hard reset.
+ * There you have it.
+ *
+ * The timer takes 23 bits of a 64 bit register (?) as a count value,
+ * and decrements the count every microsecond, for a max value of
+ * 0x7fffff usec or about 8.3ish seconds.
+ *
+ * This watchdog borrows some user semantics from the softdog driver,
+ * in that if you close the fd, it leaves the watchdog running, unless
+ * you previously wrote a 'V' to the fd, in which case it disables
+ * the watchdog when you close the fd like some other drivers.
+ *
+ * Based on various other watchdog drivers, which are probably all
+ * loosely based on something Alan Cox wrote years ago.
