Lennert Buytenhek e4fe19819e [PATCH] ARM: 2701/1: free up ixp2000 timer 4 for the watchdog ... Patch from Lennert Buytenhek The IXP2000 has four timers, but if we're on an A-step IXP2800, timer 2 and 3 don't work. We need two timers for timekeeping (one for the timer interrupt and one for tracking missed jiffies), so on early IXP2800s we have no other choice but to use timer 1 and 4 for that, but on all other IXP2000s we'd rather leave timer 4 free since that's the only timer we can use for the watchdog. So, on buggy IXP2000s (i.e. the A-step IXP2800) we use timer 4 for tracking missed jiffies, and on all all non-buggy IXP2000s (i.e. everything but the A-step IXP2800) we use timer 2. On a pre-production IXP2800, this patch should print these messages on boot: Enabling IXP2800 erratum #25 workaround Unable to use IXP2000 watchdog due to IXP2800 erratum #25 On any non-buggy IXP2800 (as well as on IXP2400s) you shouldn't see anything at all, and the watchdog should be usable again.
