2011-08-11ARM: mmp: Change the way we use timer 0 as clockevent timer.Lennert Buytenhek1-12/+35
Instead of setting up a match interrupt for 'current_time + delta' on ->set_next_event(), program timer 0 to count down from 'delta - 1' and trigger an interrupt when it reaches zero.

2011-08-11ARM: mmp: Also start timer 1 on boot.Lennert Buytenhek1-6/+9
Currently, arch-mmp/time.c uses timer 0 both as a clocksource timer and as a clockevent timer, the latter by setting up a comparator interrupt to match on 'current_time + delta'. This is problematic if delta is small enough, as that can lead to 'current_time + delta' already being in the past when comparator setup has finished, leading to the requested event not triggering. As there is also a silicon issue that requires stopping a timer's counter while writing to one of its match registers, we'll switch to using two separate timers -- timer 0 as clockevent timer, which we'll start and stop on every invocation of ->set_next_event(), and timer 1 as clocksource timer, which will be free-running. This first patch enables timer 1 on boot, so that we can use it as clocksource timer.

2011-05-07ARM: zImage: remove the static qualifier from global data variablesNicolas Pitre1-1/+1
To be able to relocate the .bss section at run time independently from the rest of the code, we must make sure that no GOTOFF relocations are used with .bss symbols. This usually means that no global variables can be marked static unless they're also const. Let's remove the static qualifier from current offenders, or turn them into const variables when possible. Next commit will ensure the build fails if one of those is reintroduced due to otherwise enforced coding standards for the kernel.
