Does this mean that this comment which is already in the driver is wrong? It alludes that "Book-E" is synonymous with "e500". /* If the kernel parameter wdt=1, the watchdog will be enabled at boot. * Also, the wdt_period sets the watchdog timer period timeout. * For E500 cpus the wdt_period sets which bit changing from 0->1 will * trigger a watchog timeout. This watchdog timeout will occur 3 times, the * first time nothing will happen, the second time a watchdog exception will * occur, and the final time the board will reset. */ #ifdef CONFIG_FSL_BOOKE #define WDT_PERIOD_DEFAULT 38 /* Ex. wdt_period=28 bus=333Mhz,reset=~40sec */ #else #define WDT_PERIOD_DEFAULT 3 /* Refer to the PPC40x and PPC4xx manuals */ #endif /* for timing information */ -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
