2011-08-21ARM: introduce atag_offset to replace boot_paramsNicolas Pitre
The boot_params member of the mdesc structure is used to provide a default physical address for the ATAG list. Since this value is fixed at compile time and sometimes based on constants such as ARCH_PHYS_OFFSET, it gets in the way of runtime PHYS_OFFSET and CONFIG_ARM_PATCH_PHYS_VIRT usage. Let's introduce atag_offset which should contains only the relative offset from PHYS_OFFSET instead of an absolute value, in preparation to move all instance of boot_params over to it.

2011-08-11ARM: mmp: Change the way we use timer 0 as clockevent timer.Lennert Buytenhek
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 Buytenhek
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.

2011-08-10omap: timer: Set dmtimer used as clocksource in autoreload modeHemant Pedanekar
If CONFIG_OMAP_32K_TIMER is not selected and dmtimer is used as clocksource, the timer stops counting once overflow occurs as it was not set in autoreload mode. This results into timekeeping failure: for example, 'sleep 1' at the shell after the timer counter overflow would hang. This patch sets up autoreload when starting the clocksource timer which fixes the above issue. Signed-off-by: Hemant Pedanekar <hemantp@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
